Description: Hydrophilic and Hydrophobic Polyether Polyurethanes And Uses Therefor This application claims the benefit of United States Provisional Application No. 60/024,526 entitled Hydrophilic Hydrophobic Polyether Polyurethanes filed by the applicants on August 26, 1996 and United States Provisional Application No. 60/040,094 entitled Hydrophilic and Hydrophobic Polyether Polyurethanes and Uses Therefor filed by the applicants on March 7, 1997. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to novel amphiphilic polyether polyurethanes which can be converted into, low encrustation, swellable, soft, biocompatible, hydrated unitary materials having specific hardness and swellable properties and superior wet tear and tensile strengths for use in intravenous, central venous, dialysis, and cardiovascular catheters, vessels, ports, synthetic veins and arteries, gaskets, medical stents, drug delivery systems, medical, cosmetic, shaving and industrial applications. The present invention also relates to novel polyether polyurethanes which can be converted into polymers which form spreadable, foams, solutions, dispersions and gels for use as creams, lotions, antiperspirants, emulsifiers, hair conditioners, drug and fragrance delivery systems, and coatings of rubber products, and which form breathable, nongreasy, water-resistant, tough, biocompatible, soft, and lubricious films. 2. Description of the Related Art. Hydrophobic and hydrophillic polymers are known and have been used for forming articles such as catheters and body implants with improved swelling properties. U.S. Patent No. 4,883,699 describes a body implant comprising a multiple phase polymer having one phase with a substantially non-hydrophilic polymer and another phase having a hydrophilic polymer. This swollen and softened material has high strength. The polyurethane is hydrophobic and the hydrophilic material is polyethylene oxide, which is susceptible to leaching, eluting from water. Further, the hydrophobic and hydrophilic materials are blended together, to form a composite. The swelling rate depends upon the water reaching the hydrophilic material and its rate is slowed by the surrounding hydrophobic polymer. U.S. Patent No. 4,994,047 ('047 patent) describes a swellable cannula formed of concentric inner and outer hydrophilic and substantially non-hydrophilic layers. The hydrophilic layer is at least 2/3 of the cross-sectional layer of the wall of the cannula. Polyoxyethylene oxide is used as the hydrophilic material. This patent suggests that swelling and softening polymers described in U.S. Patents 4,359,558, 4,424,305, 4,454,309, and 4,439,583 may be incoφorated into the cannula as hydrophilic materials. The polyurethane-diacrylate polymers are not readily extrudable because the diacrylate monomers form cross-linked networks, possibly even cross-linking the polyurethanes. The '047 patent has the shortcoming that the rate of softening of the inner hydrophilic layer is low, and the use of an outer hydrophilic layer can quickly swell the outside of the cannula, but the diameter of the cannula does not increase until its unstable layer is hydrated. U.S. Patent Nos. 3,822,238 and 3,975,350 describe a class of hydrophilic polyether polyurethanes containing about 0.3% of water. The hydrophilic polyurethanes absorb water and are cross-linked. The softness-hardness ratio of the polymers was modified by varying the ratio of soft (- OC2 H4-) units to hard alkylene units of (-C2 H OC2 H4-). The increase in hard units of the polymers increases rigidity of the polymer. An increase in soft units of the polymers results in the polymers being weak, especially in the wet and swollen state. The cross-linked polymer does not lend itself to extrusion into tubing with precise dimensions. U.S. Patent No. 4,789,720 of common ownership with the present disclosure overcame some of the above described shortcomings. A hydrophilic polyurethane is formed comprising polyoxyethylene glycol and polyoxypropylene glycol (PPG) and water in the reaction mixture of less than about 0.5% weight percent. The polyurethanes are particularly useful for body implants and feeding tubes. This patent teaches the use of PPG imparts higher dry and wet tensiles to the polymers without substantially diminishing their hydrophilic properties. The use of large amounts of PPG has the drawback of causing considerable blocking of the polymers and reducing the hydrophilicity of the polymer. This reduction in hydrophilicity is disadvantageous in certain applications such as medical device products in which it is advantageous to have high water contents and expansions. U.S. Patent No. 5, 120,816, of common ownership with the present disclosure, describes a polyurethane resin having improved tear strength in which the amount of water in the reaction mixture is in the range of about 1.0% to about 2.5% weight percent. The reaction product includes a diol formed of a long chain polyoxyethylene glycol and a medium chain polyoxyethylene glycol. The polymers have the shortcoming of not being readily extrudable. U.S. Patent No. 5,102,401 ('401 patent) teaches the use of a hydrophobic polymer coextruded over a hydrophilic polymer made with aromatic and aliphatic diisocyanates, in order to reduce the rate of swelling. The swelling rates for the uncoated catheters are 10% in one minute and 21% after 10 minutes. The swelling rate for the hydrophobic coated catheter reached 3.6% in four minutes and 14.7% in 10 minutes. These values were superior to those for a noncoated hydrophilic expandable catheter such as 20 gauge Streamline®, Menlo Care, Inc., Palo Alto, California catheter, described in the preceding patents, which reached 9% swelling in 60 minutes. Typically, nurses and doctors insert and remove needles within two to three minutes, and want the catheter to swell quickly to a high value. Accordingly, the catheters described in the '401 patent have the shortcoming of not swelling fast enough to meet the needs of health-care professionals. U.S. Patent No. 5,000,955 describes a thermally reversible gel comprising a polyether polyurethane formed using a mixture of anhydrous polyoxyethylene diols, alkylene glycol and an aliphatic diisocyanate. The viscosities of the gel drops as the temperature was increased from room temperature to body temperature. U.S. Patent No. 5,273,742 describes solutions of polyether polyurethanes for use in eye surgery and arthritic operations. SUMMARY OF THE INVENTION It has now been found that careful selection and control of the type and amount of the alkylene glycol, hydrophobic and hydrophilic diols, the type, molecular weight and ratios of the hydrophilic to hydrophobic polyoxyalkylene diol and of isocyanate to hydroxyl groups, the average molecular weight of the diol component, and the amount of water in the reaction mixture within very small ranges, produces a novel amphiphilic polyether polyurethane having improved properties such as high slip, high Shore A Hardness values, and high wet tensile and tear strengths at low to moderate hydrophilicity. The polyurethane can be formed in a one-shot polymerization in which all ingredients are combined at the same time. According to one embodiment of the present invention, an amphiphilic polyether polyurethane is produced by reacting (A) a diol component comprising a polyoxyalkylene diol, (B) an alkylene glycol, (c) a diisocyanate, and (D) water in an amount constituting from about 0 20% to about 0.80% of the combined weight of the reaction ingredients; in which the ratio of NCO to OH in the water, diol and glycol mixture is from about 0.70 to about 1.1. The amount of diisocyanate can be from about 1% to about 70% in the reaction mixture. The resulting polymer is an amphiphilic polyether polyurethane having certain hydrophilic and hydrophobic polyoxyalkylene units, so called soft segments and alkylene units, so-called hard segments connected through urethane linkages. The polymer chain also includes precise amounts of urea groups which originate from the reaction of water with isocyanate groups and which urea groups enhance the dry and wet hardness and tensile strength of the polymer. It has been found that precisely controlling the combination of the different groups in specific proportions produces improved polymer properties such as extrudability, hydrophilicity, high dry and wet tear and tensile strength, flexibility, soft feel, high slip, superior biocompatibility, and desired expansion in aqueous media. Preferably, a hydrophilic diol of poloxyethylene diol and a hydrophobic diol selected from polyoxytetramethylene diol, polyoxypropylene diol, polyether polycarbonate diol and polydimethylsiloxane polyoxyalkylene copolymer is used in the reaction mixture The polyurethane has a low water absoφtion value of about 0 1% to about 45% after 24 hours in water and a low expansion value of about 0 1% to about 30% in 24 hours in water Substrates can be coated with the amphiphilic polymers having more hydrophobic properties and then biocompatible hydrophilic polymers can be coated over the amphiphilic polymers to regulate the leaching of drugs Also, hydrophobic polymers can be coated over the hydrophilic materials to delay the onset of swelling and of leaching of drugs in aqueous media The polymers are specifically adapted as tubing for use as infusion therapy catheters such as intravenous and peripherally inserted catheters, dialysis catheters, cardiovascular catheters, stents, and ports Also, the polymers can be used in drug delivery systems to retain drugs for longer periods than more hydrophilic polymers, and as a prime coat over hydrophobic surfaces for hydrophilic materials which do not bond to hydrophobic surfaces The hydrophilic and hydrophobic polyether polyurethanes of this invention impart enhanced slip, softness, a smooth feel, and biocompatability to the surfaces for use in shaving systems The polymers can be coated on metal, silicon, elastomers, nonwoven cloth, latex rubber, polyolefins, polstyrene and hydrophillic polymers In another embodiment of the invention, in particular for certain medical device and cosmetic applications, the amphiphilic polymers are produced from (A) a hydrophobic polyoxypropylene diol having a molecular weight of about 400 to 3000, (B) an alkylene glycol, preferably ethylene glycol and diethylene glycol, (C) diisocyanate; (D) water in the amount compπsmg about 0 25% to about 0 7%, and (E) a minor portion of a polyoxyethylene diol having a molecular weight of about 400 to about 10,000, the ratio of NCO to OH in the water, diol, and glycol mixture being about 0 60 to about 1.2 The polyurethane has a water absoφtion value of about 30% to about 50% and an expansion value of about 10% to about 35% after 24 hours in water The polymers of this embodiment are particularly useful in medical devices, more specifically for use as infusion therapy catheters, including peripherally inserted catheters, intravenous catheters (IV), central venous catheters, dialysis catheters, cardiovascular catheters, shaving products, and synthetic heart valves, stents, ports, introducers, valves, shunts, breathable and water-resistant films, cosmetic, medical and therapeutic lotions and creams, and for biocompatible extrudable materials which soften and swell to controlled amounts. Also, the polymers can be used as coatings of elastomers, polymers, glass, including treated and untreated latex rubber and polyolefins such as polyethylene and polypropylene, polystyrene, high impact polystyrene, polyether polyamides, polyurethane, polyurethane-polycarbonate, and the like, metals including stainless steel, aluminum, brass, bronze, copper, silicon, silicon dioxide, nickel and chrome coated metal, brass, bronze, silicon chips, and the like, natural and nonwoven materials. The substrates can be coated with a primer and also can be treated with plasma energy and oxidative gases to enhance bonding of the primer and the topcoat. The amphiphilic polyether polyurethanes of this invention bond to a wide variety of substrates, impart enhanced slip and biocompatiblity to the surfaces, and also can serve as a primer for more hydrophilic polymers. The amphiphilic polyether polyurethanes are especially valuable for certain medical devices and shaving systems because the polyurethanes of this invention have the advantages of extrudability, improved slip compared to hydrophobic polymers and elastomers including polyurethane, polystyrene, and the like, improved feel and biocompatability, superior dry and wet tensile and tear strengths, and high dry and wet Shore A hardness values. In these cases, low hydrophilicity is needed to reduce expansion upon exposure to water, and unexpectedly minor amounts of hydrophilic diols impart improved biocompatability, slip and compatability with hydrophilic materials compared to polymers without amounts of polyoxyethylene diol. Alternatively, an amphiphilic polyether polyurethane having improved wet and dry strength comprising the reaction product of a mixture of a hydrophilic diol of polyoxyethlene diol having a number average molecular weight of about 800 to about 20,000, the amount by weight of the hydrophilic diol in the reaction mixture being from about 10% to about 50%; at least one hydrophobic diol selected from polyoxytetramethylene diol, polyoxypropylene diol, an alkylene glycol, an organic diisocyanate; and water in an amount by weight of about 0.20% to about 0.8% of the reaction mixture, the ratio of NCO to OH of the diols, the alkylene glycol and the water being from about 0.70 to about 1.1, wherein said polyurethane has an absorption value of about 20% of about 60% of water after 24 hours in water and an expansion value of about 30% to about 50% after 24 hours in water. This polyurethane can be used to form a shape structure such as tubing, catheters, valves, introducers, shunts, ports, stents, synthetic veins and synthetic arteries. In addition, a polyether polyurethane having improved slip is formed from the reaction product of a diol selected from polyoxyethylene diol having a number average molecular weight of from about 400 to about 20,000, the amount by weight of the polyoxyethylene diol in the reaction mixture being at least 60%, polyoxypropylene diol having a number average molecular weight of about 200 to about 4,000, a polyoxytetramethylene diol having a number average molecular weight of about 200 to about 4,000, a polyetheφolycarbonate diol having a number average molecular weight of about 1000 to about 2,200, a polydimethylsiloxane polyoxyalkylene copolymer diol having a number average molecular weight of about 500 to about 3,000, and a polybutylene oxide having a number average molecular weight of about 1000 to about 3,000; an alkylene glycol, an organic diisocyanate; and water in an amount by weight of from about 0.001% to about 0.8% of the reaction mixture, the ratio of NCO to OH of the diols, the alkylene glycols and water being from about 0.85 to about 0.99. The polyurethane of this aspect can preferably be used to form an article or a coating. The coating can be applied to metal, plastic, woven cloth, nonwoven cloth, rubber, hair, glass, silicon, chlorinated elastomers and nonchlorinated elastomers, razor strips, polymers and silicon chips. A coating which is adapted to be applied to rubber gloves can be formed of a polyether polyurethane formed from the reaction product of a polyoxyethylene diol, and water in an amount by weight of from about 0.65% to about 0.75% of the reaction mixture, the ratio of NCO to OH of the diols, the alkylene glycols and water being from about 0.55 to about 0.75 and a filler in an amount by weight of about 0.1% to about 80%. In an alternate aspect of the invention, an amphiphilic polyurethane is formed from a reaction product of a hydrophilic diol of polyoxyethylene diol having a number average molecular weight of about 4,000 to about 10,000 in an amount of about 45% to about 96% and polyoxyethylene diol having a number average molecular weight of about 600 to about 2,000 in an amount of about 0.5% to about 10%,a hydrophobic polyoxyalkylene diol selected from at least one hydrophobic diol such as polyoxytetramethylene diol having a number average molecular weight of from about 600 to about 3,000, polyoxypropylene diol having a number average molecular weight of from about 400 to about 2,500, a polyether polycarbonate diol having a number average molecular weight of about 1,000 to about 2,000, and a polydimethylsiloxane polyoxyalkylene copolymer having a number average molecular weight of about 500 to about 3,000, water in an amount by weight of about 0.005% to about 0.30% of the reaction mixture, the ratio of NCO to OH of the diol and water by about 0.80 to about 0.99. A cream, gel, film, solution coating and dispersion can be formed from the polymer of this aspect. Alternatively, a cream or lotion can be formed of a polyurethane formed from a reaction product of a mixture of a diol component of a high molecular weight polyoxyalkylene diol selected from polyoxyethylene diol having a number average molecular weight of about 400 to about 20,000, polyoxypropylene diol and polyoxytetramethylene diol having a molecular weight from about 400 to about 3000, an alkylene glycol selected from ethylene glycol, diethylene glycol, and triethylene glycol, an organic diisocyanate and water in an amount comprising from about 0.01% to about 0.6% of the reaction mixture. Alternate embodiments of the invention include a solution, film or gel formed of the reaction product of a diol component comprising a polyoxyethylene diol having a number average molecular weight of about 400 to about 20,000, an alkylene glycol selected from ethylene glycol, diethylene glycol, and triethylene glycol, an organic diisocyanate, water in an amount comprising from about 0.001% to about 0.3% of the reaction mixture. Detailed Description of the Invention The present invention is based on the discovery that a class of amphiphilic polyether polyurethanes more fully described herein formed from the reaction product of a diol component, an alkylene glycol, a diisocyanate and water are advantageous in medical device, drug delivery, industrial, and cosmetic applications. Infusion therapy catheters and stents formed of the amphilic polyurethane have improved soft feel, dry and wet strength integrity, dry and wet Shore A Hardness values, and controlled expansion upon hydration. Creams, foams, lotions, barrier solutions, emulsions, dispersions, and gels formed of the polymers form breathable, spreadable, water-resistant, and non-greasy films for use in medical and cosmetic products. Coatings of the amphiphilic polyether polyurethanes of this invention on hydrophobic surfaces including elastomers and plastics such as latex rubber, ethylene and propylene co- and terpolymers, high impact polystyrene, butadiene and styrene copolymers and the like, form tenacious bonds that have improved slip. The coatings can be used as a primer for application of high slip hydrophilic polymers. In cosmetic and shaving applications, the polymers of the present invention provide smoothness, enhanced slip, soft feel, superior dry and wet strength, breathability, non-greasy feel, water-resistance, excellent compatability with hydrophilic materials, and controlled expansion in aqueous media. A first aspect of the present invention pertains to an amphiphillic polyether polyurethane formed from the reaction product of a diol component which includes a mixture of hydrophilic and hydrophobic polyoxyalkylene diols. Preferably, the diol component comprises a hydrophilic diol having a portion of polyoxyethylene diols having a number average molecular weight of from about 400 to about 10,000 of about 15% to about 45% mixed with a portion of hydrophobic diol of about 15% to about 30% having about 10% to about 25% of polyoxytetramethylene diol having a number average molecular weight of about 600 to about 3000 and a hydrophobic diol of about 1.0% to about 25% polyoxypropylene diol having a number average molecular weight from about 400 to about 2500, thereby providing a hydrophobic diol component with a number average molecular weight of about 1000 to about 3000. The diol component is mixed with about 0.5% to about 10% by weight of an alkylene glycol selected from ethylene glycol, propylene glycol, 2-ethyl-l,3- hexanediol, tripropylene glycol, triethylene glycol, 2,-4-pentane diol, 2-methyl-l,3-propanediol, 2,- methyl-1,3- pentanediol, cyclohexanediol, diethylene glycol, cyclohexanedimethanol, dipropylene glycol, and mixtures thereof, an organic diisocyanate and a water equivalent in an amount comprising from about 0.30% to about 0.7% of the reaction mixture in an equivalent mole weight ratio of NCO to OH of the diol, alkylene glycol and water of from about 0 60 to about 1.2. The polymers formed in this aspect of the invention have intermediate water absoφtion values of about 30 to about 50% and linear expansion values of about 10% to about 30% after 24 hours in water Alternatively about 1% to about 30% of polyetherpolycarbonate diols (PCD) of about 1000 to about 2000 number average molecular weight, polydimethylsiloxane polyoxyalkylene copolymers (PDMSD) of about 500 to about 3000 number average molecular weight, and polybutylene oxides (PBO) having a number average molecular weight of about 1000 to about 2200, preferably 2000, can be used as the hydrophobic diol The polyether groups in PCD are preferably alkylene glycols, such as for example, butane diol, propylene glycol, pentane diol and hexane diol The polyoxyalkylene diols in PDMSD are preferably polyoxyethylene diols and polyoxypropylene diols, more preferably polyoxyethylene diols, and most preferably polyoxyethylene diols having a number average molecular weight of about 200 to about 2000, preferably from about 200 to about 1000. For example, the polyoxyethylene diols are available from Union Carbide Coφoration under the trademark and designation Carbowax, such as Carbowax® 3360, Carbowax® 4500, Carbowax® 8000, and Carbowax® 1450 wherein numbers represent the number average molecular weight Polyoxypropylene diols are available from various sources such as from ARCO under the trademark of NIAX® PPG 1025, PPG-425, PPG-725, PPG 4025 and PPG 2025 and Acclaim 2200 and Acclaim 4200 wherein the numbers represent the number average molecular weight except in the case of Acclaim where the number average molecular weight values are 2000 and 4000 respectively. For example, polyoxytetramethylene diols are available from E I. Dupont de Nemours as Terathanes 600, 1000, 1400, 2000, 2900. Polyetheφolycarbonate diols are available, for example, from BASF as PolyTHFCD-1000 and PolyTHF CD-2000, CD4200, CD4201 and Nippollan 980 and Nippollan 981 are available from Nippoly America Coφ For example, polydimethylsiloxane polyoxyethylene copolymers are available from OSI as Silwets, Dow Corning as Q4-3667, Q2481, Q2 5211 and from GE as GE Silicones as 1 161-1 1-925, 1161-1 1-926, 1161- 1032, 1161-11-928, 88017 and polybutylene oxides are available from Dow Company as XAS.1096.01 and .05 Alternatively, block copolymers of ethylene oxide and propylene oxide having a number average molecular weight of about 1000 to about 2500 can also be used in the reaction. For example, a propylene oxide terminated block of ethylene glycol manufactured by BASF under the tradename Pluronic R and an ethylene oxide terminated block of propylene glycol manufactured by BASF under the tradename of Pluronic can be used for the polyoxyalkylene diol in the reaction. Examples of the block copolymers of the sequential addition of ethylene oxide and propylene oxide to ethylene diamine are made by BASF under the tradename of Pluronics and Pluronic R such as F64, F127, L35, L92, F68, L82, 17R2 and 25R2. Preferably the polyoxyalkylene diol used to form the amphiphilic polyether polyurethanes of this invention are formed from a combination of a hydrophilic diol of about 5% to about 20% of a polyoxyethylene diol (PED) of a number average molecular weight from about 400 to about 2000, referred to as low molecular weight, and about 10% to about 25% of a PED of a number average molecular weight from about 2500 to about 5000, referred to as high molecular weight, with hydrophobic diols of about 1% to about 25% of a polyoxypropylene diol having a number average molecular weight of about 400 to about 2500, preferably from about 1000 to about 2000, and from about 10% to about 30% of a polyoxytetramethylene diol having a number average molecular weight of about 600 to about 2500, preferably from about 1000 to about 2000.

Preferably the average molecular weight of the polyoxyalkylene diol component, including the hydrophilic and hydrophobic diol, is from about 1500 to about 3000. Preferably, the amount of polyoxyalkylene diol used in the reaction is from about 40% to about 70%, more preferably from about 45% to about 60%. Preferably, the amount of polyoxypropylene diol used in the reaction mixture is from about 3% to about 20%, more preferably in the amount of about 4% to about 15% of the reaction mixture, and most preferably in the amount of about 5% to about 10% of the reaction mixture. Alternatively, the polyoxyethylene diol can be formed of about 20% of a polyoxyethylene diol having a number average molecular weight of about 6000 to about 10,000 and about 10% to about 25% of a PED of a number average molecular weight of from about 2500 to about 5000. The increased molecular weight of the hydrophilic diol in the amphiphilic polyurethane imparts higher hydrophilicity, higher water absoφtion, higher water expansion, higher dry Shore A Hardness values and lower wet Shore A Hardness values. Alternatively, the polyoxyethylene diol can include about 12% to about 18% of a polyoxyethylene diol having a number average molecular weight of about 400 to about 1000 and about 10% to about 15% of polyoxyethylene diol having a number average molecular weight from about 1000 to about 2000. Polyoxyethylene diols having a number average molecular weight of about 400 to about 1000 can be used in combination with about 12% to about 20% of polyoxypropylene diol, in order to obtain high dry and wet tear and tensile strength polymers with enhanced slip, soft and smooth feel, low expansion and water content after immersion in water, and improved bondability to hydrophobic surfaces. Alkylene glycols are available from chemical supply houses. For example, ethylene glycol and diethylene glycol are available from Aldrich Chemical Company. Preferably, the amount by weight of the alkylene glycol used in the reaction mixture is from about 3% to about 20%, and more preferably from about 4% to about 12%. Preferably the alkylene glycol is triethylene glycol, diethylene glycol, and ethylene glycol, and more preferably the alkylene glycol is ethylene glycol. For this aspect, the preferred amount of the ethylene glycol is from about 4% to about 10%. Preferably the amount of water by weight in the reaction mixture is in the range of from about 0.25% to about 0.65%, and more preferably from about 0.30% to about 0.60% of the reaction mixture. The ratio of NCO to OH of the hydroxyl groups from the diols, alkylene glycol, and water in the reaction mixture is preferably in the range from about 0.80 to about 1.0 and most preferably from about 0.90 to about 0.99. The sum of all ingredients, including the diols, glycols, water, and diisocyanate in the reaction mixture totals 100 parts by weight. The diisocyanate used in the present invention can include both aliphatic and aromatic types and mixtures thereof. Still more preferably, isocyanates are methylene bis(-cyclohexyl-4- isocyanate) and methylene bis(-phenyl-4-isocyanate), and more preferably is methylene bis(- cyclohexyl-4-isocyanate). Other examples of diisocyanates are trimethyl hexamethylene diisocyanate and isophorone diisocyanate. Representative examples of the preferred aliphatic diisocyanates include, but are not limited to tetramethylene diisocyanate, hexamethylene diisocyanate, trimethylene diisocyanate, trimethylene hexamethylene diisocyanate, cyclohexyl 1,2-diisocyanate, cyclohexylene 1 ,4-diisocyanate, and aromatic diisocyanates such as methylene bis(-phenyl-4-isocyanate) (MDI), 2,4-toluene diisocyanates and 2,6-toluene diisocyanates. Also suitable are the isocyanate equivalents which form urethane linkages as exemplified by nitrile carbonates, such as adiponitrile carbonate of the formulas (U.S. Patent No. 4,810, 543 of common ownership therewith). The amount of diisocyanate in the reaction mixture can vary from about 1% to about 70%, preferably from about 20% to about 60%, and more preferably from about 30% to about 55%. The polymers are prepared by reacting the polyoxyalkylene diols with the diisocyanates. In forming the polyurethane of the present invention, the diol and glycol components are formed into a homogeneous mixture which is then reacted with diisocyanate, the reaction is catalyzed with known catalysts such as tin salts and organic tin esters such as dibutyl tin dilaurate and stannous octoate. Preferably the catalysts used in the reactions are stannous octoate and dibutyl tin dilaurate, manufactured by Air Products and Chemicals as To and T 2 Alternatively, in forming a polyurethane with methylene bis(phenyl-4-isocyanate) MDI the catalyst can be omitted. In an alternative method, a semi-batch reaction is used in which the diols are heated and the mixture is analyzed for water; and a predetermined amount of additional water is added. The catalyst is added to the mixture. Diisocyanate is added to another reactor and heated under dry nitrogen. Two streams of heated reactive mixtures are mixed in a predetermined ratio in a tube and allowed to flow into a pan, extruder, static and dynamic mixers, trough, conveyor belt or other container. The mixture is allowed to react further at a temperature from about 20° to about 140°C, preferably from about 30° to about 135°C, more preferably from about 40° to about 130°C, and most preferably from about 60° to about 120°C for about one minute to about one week, preferably from about five minutes to about 240 minutes, more preferably from about 10 minutes to about 120 minutes. The reaction can be completed at room temperature. The polymers can be cut into strips by a bandsaw and then granulated into small flakes or granules using a granulator and chipper. The particle size of the granules depends upon the mesh size of the screen. The blocks of polymers can be granulated and then cryogenic ground or pulverized to powder. Alternatively, the reaction mixture can be fed to continuous trough-type dryers and extruders, chopped into granules, and then fed to a pulverizer, or used without further treatment. It has suφrisingly been found that controlling several factors in the reaction mixture provides polymers with valuable properties for effective use in medical, cosmetic, and industrial applications, more specifically for use in medical devices and as coatings of metals, glass, hair, elastomers and plastics. It has been found that controlling precisely the type, total amount and molecular weight of hydrophilic and hydrophobic diols, type and amount of alkylene glycol, ratio of isocyanate to hydroxyl groups and total amount and number average molecular weight of polyoxyalkylene diol provide properties of the polymer for effective use in tubing for medical devices, industrial applications, and coatings. It has been found experimentally, for example, that a polymer with a moderate amount of urea groups which is tough, extrudable, flexible, biocompatible, with requisite wet and dry hardness values and desired expansion in water can be obtained by controlling the urea groups, number average molecular weight of the polyoxyalkylene diol, ratios of hydrophobic to hydrophilic diol and high to low molecular weight hydrophilic diol of PED, type and amount of the hydrophobic polyoxyalkylene diol, and type and amount of alkylene glycol. It has been found that too few urea groups in the polymer produce soft, low tensile polymers, and too many urea groups in the polymer yield hard, less flexible polymers. The polymers of this aspect of the invention have the optimum and preferred balance of properties for use in certain medical devices and cosmetic and shaving applications, especially for components, accessories and catheters for infusion therapy, biliary and urinary stents and as coatings.

The polymers can be used to prime hydrophobic substrates over which a topcoat of a more hydrophilic polymer is coated. It has been found that amphiphilic polyether polyurethanes formed of this aspect comprising about 0.1% to about 30% polydimethysiloxanepolyoxyethylene copolymers in the reaction mixture are soft, do not block and have improved oxidative resistance. Polymers comprising about 0.5% to about 30% of polyetheφolycarbonate diols and mixtures thereof in the reaction mixture have been found to be less blocking than those with equal amounts of polyoxypropylene diols, have superior dry and wet stress-strain properties and improved oxidative resistance. The polymers are valuable for medical device, industrial, cosmetic, and shaving applications because of their soft feel, flexibility, toughness, breathability, excellent dry and wet strength, low expansion, superior biocompatability, low kinkability, compatability with other hydrophilic materials, low drug release rates and high slip. The polymers are especially useful as scar flatteners, for softenable-nonswellable catheters, and cosmetic and shaving applications because of their soft feel, breathability, superior compatability with more hydrophilic materials, improved slip compared to prior art hydrophobic polymers, superior dry and wet tensile and tear strength, and low expansion. The polymers can be used with and without fillers for incoφorating fragrants and coating latex rubber and synthetic rubber goods, including gloves, condoms, and coating fingers, because of improved donnability, breathability, hypoallergenicity, smoothness, and enhanced slip without use of powder and pretreatment.

Fillers can be added to the polymer from about 0.1% to about 60% of the total loading. For rubber goods, preferably the loading is from about 0.5% to about 50%. The filler loadings are based upon polymer solids. The polymers of the second aspect of the invention can be used for delivery systems, and to coat silicon chips used for computer and medical devices. By using primers having different hydrophilicity, as described in this invention, the surface properties can be modified. It is desirable in analyzing certain proteins to apply a hydrophilic polymer over silicon metal as a primer, and then topcoat with a less hydrophilic polymer, such as one described in aspects one and two. It may be valuable to form a device using the low expansion polymers described in aspects one and two, eliminating the need to coat the silicon metal. Elution rates with chemicals, drugs and protein, cells, enzymes incoφorated into hydrophilic polymers can be controlled by coating a hydrophobic coating over the hydrophilic coating. And drugs can be incoφorated into an aqueous media, and their reaction with enzymes, cells, and proteins incoφorated into the coating can be observed and measured using computer chips and lasers.

For example, latex and synthetic rubber gloves and rubber products can be coated with an amphiphilic polymer described in the second aspect of this disclosure and then topcoated with the more hydrophilic high slip polymer described in this aspect. The concentration of polymer in solution is about 0.01% to about 10%, preferably about 0.1% to about 6% and most preferably about 0.15% to about 3.5%. It has been found that the addition of about 0.1% to about 50% of desiccant fillers such as ZeoChem, Zeolites, molecular sieves, glycerine, barytes, and calcium sulfate in the primer and topcoats of coatings of rubber products reduce tack and increases water absoφtivity at low humidity levels. It has also been found that the use of dessicant fillers, preferably the use in the coating of from about 0.5% to about 25% of filler, based upon polymer solids unexpectedly improves dry, damp and wet donnability. The coated products can be used in medical, cosmetic, and industrial applications. Products which can be coated include polyethylene stylets, woven and nonwoven cloths, polyester and Teflon cloth made under the tradenames of Gortex and Dacron for medical and industrial applications, cotton, silk, and sutures, stainless steel needles and guide wires for use in urinary, cardiovascular, and infusion therapy catheters, elastomeric type exam, surgeon, dental, electronic, automotive, and industrial gloves, cosmetic products and medical sorting devices, medical gloves, condoms, and other rubber gloves products. The high slip polymers of the fourth aspect can impart rapid softening, high slip, hypoallergenicity, smoothness, high and rapid water absoφtivity, excellent wet strength, high expansion, biocompatability, lubricity and breathability to the coated product. For use in coating rubber products such as surgical, medical, clean-room, electronic and industrial gloves and condoms, and to further enhance damp and wet donnability, the hydrophilic polymers of the fourth aspect of the present invention can be mixed at a concentration of polymer solution of about 0.1% to about 6% with about 0.01% to about 20%, based on polymer solids, of hydrophilic polymers such as polyvinylpyrrolidone and polyoxyethyleneoxide, and with polymers described in the first and second aspects of this invention made with polydimethylsiloxane polyoxyethylene copolymers. Preferably the polymers for superior damp and wet donnability are hydrophilic polymers of this aspect formed from a polyether polyurethane formed from the reaction product of a diol selected from the group consisting of polyoxyethylene diol having a number average molecular weight of from about 400 to about 20,000, the amount by weight of the polyoxyethylene diol in the reaction mixture being at least 60%, with about 0.65% to about 0.75% water at a NCO to OH ratio of about 0.51 to about 0.65 methylene bis(-cyclohexyl-4-isocyanate) using isocyanate DW. Preferred fillers are added to the polymer of about 0.5% to about 50% of the Zeolite type filler, preferably Type 5 A. Preferably, into a concentration of the polymer of about 0.01% to about 10% in a coating solution, about 0.3% to about 10% of polymers comprising about 1% to about 10% of PDMS is incoφorated into a coating mixture used for coating rubber products. The coating mixture has the advantage of providing simplicity for the coating which can be applied on-line at any stage of the dipping process without curing or cross-linking the polymers and without leaving any residual odor on the hands due to amines and other lubricants. Small amounts of commercial antioxidants can also be added to prevent oxidation during the curing of the rubber. The coating mixture can be dissolved in ethanol and water solvent and applied during formation of a glove by dipping and spraying methods. Alternatively, polymers of this aspect of the present invention comprising polydimethylsiloxane polyoxyethylenecopolymers having a number average molecular weight of about 500 to about 3000 can be used in aqueous dispersions or blended with other hydrophilic polymers in the dispersion and the dispersion can be used to coat rubber products. The polymers can also be used in coatings of suture needles, sutures, needles, scalpels and metals. It has been discovered that the high slip polymers of the present invention because of their high hydrophilicity and inherent biocompatible nature can be used to transport proteins, drugs, cells, blood and vitamins without significantly modifying their structure and effectiveness. The polymers can be used as coatings of blood collection containers, coronary, urinary and biliary stents, and infusion therapy catheters. The hydrophilic polymers of this aspect do not significantly alter the structure and composition of the complex proteins. This property enhances their use in wound dressings, sorting devices, coatings of rubber products, catheters, guide wires, cannula, ports, introducers, valves, tubing, and a wide range of medical devices. The high slip polymers allow aqueous solutions of a wide range of molecules to pass through a sorting medical device such as a computer chip because of high slip, biocompatability, high water absorptivity, low to nonadsoφtion of complex proteins and cells, and smoothness of the coating. The high slip polymers of this aspect comprising about 0.03% to about 0.2% by weight water in the reaction mixture and about 0.88 to about 0.98 NCO to OH ratio can be used to coat metals, plastics, nonwoven and woven cloth and rubber. The high slip polymers comprising about 0.01% about 0.07% water in the reaction mixture can be used to form water soluble polymers which are spreadable for use in cosmetics, make-up and as coatings of skin, plastics, metals, and rubber. Solutions of water soluble polymer produce breathable, soft, water-absoφtive films. The high slip polymers comprising about 0.25% to about 0.5% water by weight in the reaction mixture can be extruded to form tough, water absorbable products that can be used for medical devices, cosmetics, shaving razor strips, and industrial applications. The polymers can be coextruded over other plastics possessing lower expansion values. To enhance the adhesion of the hydrophilic polymers to the hydrophobic surfaces, isocyanate primers, such as Adcote 533 made by Morton Coφoration and Desmophen 670A-80 and BL31-75 made by Bayer Coφoration can be coated onto the hydrophobic surface. Polymers comprising mixtures of hydrophobic and hydrophilic segments such as the polymers described in aspect three of this invention, and about 0.01% to about 5% of di and trifunctional acrylates and methacrylate such as trimethylol dimethacrylate, ethylene glycol dimethacrylate, zinc dimethacryiate, and about 0.01 to about 5% of a peroxide, based upon the acrylate, can be mixed into both hydrophilic and hydrophobic polymers and added separately between the layers and mixed only with the hydrophilic layer and heated to form cross-linked inteφenetrating networks which hook both hydrophilic and hydrophobic polymers. Because of their unique high hydrophilicity, the polyether polyurethanes of aspect four of this invention impart excellent biocompatibility and superior slip low protein and cell adhesion properties to medical devices enhancing their value in shunts, stents, cardiovascular and infusion therapy catheters, introducers, blood collection units, arterial and venous grafts, mechanical and synthetic heart valves, and the like. The high slip of the polyurethane polymers of this aspect enhances their use for cosmetic and shaving devices and industrial applications. Also, water soluble molecules including drugs, enzymes, and proteins can be absorbed into the high slip polymer coating because of its high absoφtivity. Water can be evaporated from the coating at about 15°C to about 40°C, and then a solution of another molecule can be passed through the device to observe the interaction at a molecular level on screen. A solution of this polymer can be applied to cuts and wounds for aiding in healing the cuts and wounds. Also, the hydrophilicity of the polymers can be further modified with about 0.1% to about 20%, preferably from about 0.3% to about 15%, of a hydrophobic polyoxyalkylene diol selected from the group of polybutylene oxide, polyoxypropylene diol, polyoxytetramethylene diol, polydimethylsiloxane polyoxyalkylene copolymer, preferably polydimethylsiloxane polyoxyethylene copolymer, and polyetheφolycarbonate diols comprising butane and hexane diol, as herein described to impede the leaching of the water soluble molecule from the coating. Alternatively, an amphilic polymer such as described in aspects one, two and three of this invention can be coated over the hydrophilic polymer which serves as the reservoir for the drug, cell, protein, chemical, material and extends the elution, thereby increasing the activity of the material. The hydrated hydrophilic polymers have a helix nature allowing long chain materials such as hydrophilic polymers, enzymes, cells, drugs, and molecules to become intertwined with the helix and form inteφenetrating networks with the hydrated hydrophilic polymer helix. The entrapped molecules and materials can exhibit their unique activity for a greater period of time than if the materials which were not captured by the helix hydrated polymer. For example, some of the heparin, long chain enzymes, materials and DNA type materials incorporated into the polymer elutes out of the hydrated structure within a short period, and the rest can remain captured within the helix for a much longer period, and retain its activity for an extended period. The coated material can be used to remove a specific virus, bacteria, cell, protein, ingredient from a solution by preabsorbing a receptor for the molecule and cell, an adsorber of the molecule and cell from the solution. The molecule containing the receptor of a particular virus can be adsorbed into the polymer, allowing a blood sample containing the virus to pass through tubing in order to adsorb and denature the virus. The diols in the fourth aspect impart biocompatibility, controlled drug delivery and fragrance leaching, lubricity, low tack and viscosity, controlled water repellency, superior wetting, and flow for use in hair conditioners, drug and fragrance delivery systems, and coatings of rubber and non- woven products. Polymers of this aspect can be extruded into water permeable and water swellable films and can be mixed with water, propylene glycol and water, and glycerine and water to form unique gels for use in wound care, cleaning fluids, oil-drilling, and delivery of drugs, and can form unique films for cosmetic, medical and industrial products. The fifth aspect of the present invention relates to creams, pastes, foams, lotions, emulsions, dispersions, solutions, coatings and gels formed from the above-described amphiphilic polyether polyurethanes. In the fifth aspect of the invention, the amphiphilic polyether polyurethanes can be blended with water, oils, humectant, drugs, herbs, vitamins, solvents, waxes, fillers and emulsifiers to thicken liquids, form emulsions and dispersions, and to form spreadable lotions, creams, solutions, amoφhous gels and coatings of rubber products for cosmetic, medical and industrial applications. The amphiphilic polyether polyurethanes can be formed of the reaction product of a polyoxyalkylene diol having a major portion of a hydrophilic polyoxyethylene diol having a number average molecular weight of about 4000 to about 10,000, a minor portion of a less hydrophilic polyoxyethylene diol having a number average molecular weight of about 600 to about 2000, a minor portion of a hydrophobic polyoxyalkylene diol having a number average molecular weight of about 200 to about 3000, an organic diisocyanate, and a water equivalent from about 0.005% to about 0.30% in an equivalent mole weight ratio of NCO to OH from about 0.80 to about 0.99. Preferably the amount of the hydrophilic polyoxyethylene diol having a number average molecularweight of about 4,000 to about 10,000 in the reaction mixture is from about 45% to about 96%, preferably from about 50% to about 92%, and most preferably from about 60% to about 90%.

Preferably, the amount of the polyoxypropylene diol is from about 0.5% about 20%, and more preferably from about 2% to about 10%. Preferably the amount of the lower molecular weight polyoxyethylene diol having a number average molecular weight of about 600 to about 2,000 is from about 0.5% to about 20%, preferably from about 1% to about 15%, still more preferably from about 2% to about 10%. Alternatively the hydrophobic polyoxyalkylene diol is a polyoxytetramethylene diol and PBO having a number average molecular weight from about 200 to about 3000, and most preferably from about 200 to about 2000. Preferably, the amount of the PBO and polyoxytetramethylene diol is from about 0.1% about 20%, and more preferably from about 0.2% to about 10% by weight of the reaction mixture. Preferably the amount of water in the reaction mixture for polymers of this aspect comprising polyoxypropylene diol and polyoxytetramethylene diol is from about 0.005% to about 0.2%, preferably from about 0.008% to about 0.15%, still more preferably from about 0.01% to about 0.10%, and most preferably from about 0.01% to about 0.08%. Preferably the ratio of NCO to OH is from about 0.80 to about 1.00, more preferably from about 0.85 to about 0.98. The amount of diisocyanate in the reaction mixture can vary from about 2% to about 70%, preferably from about 3% to about 40%, and more preferably from about 3% to about 25%. The polymers are prepared by reacting the polyoxyalkylene diols with the diisocyanates. Still more preferably, isocyanates are methylene bis(-cyclohexyl-4-isocyanate) and methylene bis(-phenyl-4- isocyanate), and most preferably methylene bis(-cyclohexyl-4-isocyanate). Alternatively, an alkylene glycol is selected from diethylene glycol, dipropylene glycol, and tripropylene glycol. The amount of the glycol in the reaction mixture is from about 0.5% to about 10%, preferably from about 1% to about 7%. Alternatively, block copolymers of ethylene oxide and propylene oxide having a number average molecular weight of about 1000 to about 2500 can also be used in the reaction mixture. Preferred block copolymers are those produced by Union Carbide Coφoration under the trademark of F 127, F68, and L35. The amount of block polymers in the reaction mixture is from about 2% to about 20%. Alternatively, the hydrophobic polyoxyalkylene diol used in the reaction mixture of the sample is a polyether polycarbonate diol (PCD) having a number average molecular weight from about 600 to about 2400, preferably from about 800 to about 2000. Preferably the diol in the PCD is selected from propylene glycol, butane diol, pentane diol, and hexane diol, more preferably butane diol and hexane diol. Preferably about 0.1% to about 20% of PCD is used in the reaction mixture, more preferably from about 0.2% to about 20.0%, and most preferably from about 0.25% to about 10.0%. Preferably the amount of water by weight in the reaction mixture is from about 0.001% to about 0.3%. Alternatively, the hydrophobic polyoxyalkylene diol is a polydimethylsiloxane polyoxyalkylenecopolymer, (PDMS) preferably PDMS in which the polyoxyalkylene diol is a polyoxyethylene having a number average molecular weight from about 200 to about 2400, preferably from about 200 to about 1500 and mixtures thereof, can be used in the reaction mixture.

For water-soluble and water-dispersible polymers comprising polydimethysiloxane polyoxyethylene copolymers, the amount of water in the reaction mixture is about 0.001% to about 0.20%, and for water-soluble, nonwater-dispersible polymers, the amount of water in the reaction mixture is about 0.20% to about 0.60%. At water levels of about 0.30% to about 0.60%, the polymers are extrudable. The ratio of NCO to OH groups is from about 0.85 to about 0.98. It has been discovered that polymers comprising polyether polycarbonate diols made with butane diol and hexane diol and having a molecular weight of about 800 to about 2000 form emulsions and thicken aqueous media. Polymers comprising polydimethylsiloxane polyoxyethylene copolymers and having a molecular weight of about 500 to about 2500 form emulsions and dispersions depending upon the concentration and type of diol, and amount of urea groups in the reaction formula. Apparently the dimethylsiloxane group is sufficiently hydrophobic to cause the polymer chain to coil. Polymers comprising polyether polycarbonate diol groups based upon butane diol and hexane diol are soluble in water and emulsify oils in an aqueous media because the polymer is extremely hydrophilic. The butane-carbonate section in the polymer forms the head and the polyoxyethylene section group forms the tail of the polymer chain to function as an emulsifier. For each type of silicone and carbonate comprising polymer, further modification of the effect can be realized by the amount of urea groups and the molecular weights of the hydrophilic diol and the alkylene diol, respectively. All these effects are unexpected for hydrophilic polyurethanes. It has been discovered that polymers made with about 0.1% to about 15% of PCD preferably from about 0.2% to about 10%, most preferably from about 0.3% to about 7% of the polyether polycarbonate diol having a number average molecular weight of about 900 to about 2000 and about 0.001% to about 0.25% of water in the reaction mixture, preferably about 0.010% to about 0.15%, more preferably from about 0.015% to about 0.07% water have unexpected properties The polymers thicken aqueous media and form spreadable, low pH, aqueous solutions and also form emulsions in the presence of hydrophobic materials such as oils, vitamins, drugs, and the like. For example, 70 grams of an aqueous solution of about 2% polymer comprising about 5% PCD made with butane diol was mixed with 12 grams of cottonseed oil and 17.5 grams of water and 0.5 gram Germaben to form a creamy emulsion with a flowable viscosity and a pH of 7.0. The cream was readily spread on the hand and formed a tough, water-resistant, breathable, non-greasy film. For example, 70 grams of an aqueous solution of about 2% polymer comprising about 1% PCD made with hexane diol_was mixed with 12 grams of cottonseed oil and 17.5 grams of water and 0.5 gram Germaben to form a creamy emulsion with a flowable viscosity of 9200 cps and a pH of 7.0. The cream was readily spread on the hand and formed a tough, water-resistant, breathable, non-greasy film. The polymer formed of 1% PCD at about 2% concentration increased the viscosity of water to 110,000 cps. The polymer can be used to prepare spreadable, breathable face and hand creams, make-up, lotions, and as thickeners for use in paints and polar materials. It has been further discovered that polymers made with about 0 4% to about 15% of polydimethylsiloxane polyoxyalkylene diols comprising about two to about ten dimethylsiloxane groups and having a number average molecular weight of about 500 to about 4000, preferably comprising polyoxyethylene diols having a number average molecular weight of about 200 to about 1500 and about 0.001% to about 0.3% water form dispersions in water for use in hair styling aids, hair sprays, mousse, gels, shampoos, face and hand creams, make-up, paints, lubricants, foams, as coatings of natural and synthetic rubber products, hair conditioners, skin care, body creams and lotions, chemicals, nutrients, disinfectant, fragrance and drug delivery systems, coatings of rubber goods, metals, and plastics It has been discovered that these polymers can decrease the viscosity of aqueous media, provide low viscosity dispersions in water, and more viscous dispersions in organic/aqueous mixtures The viscosity of dispersions comprising about 0 1% to about 80% polymer can be controlled by the molecular weight of the polydimethylsiloxane polyoxyethylenecopolymer and the molecular weight of the polyoxyethylene copolymer in the PDMS and the amount of urea groups in the polyurethane For example, an about 2% aqueous dispersion of polymer comprising about 0.035% water and about 5% polydimethylsiloxane polyoxyethylenecopolymer having a number average molecular weight of 2440, has a viscosity of 18 cps in water and 126 cps in 60/40 propylene glycol water and a 2% dispersion of polymer comprising about 0 10% water and about 5% of the silicone containing diol has a viscosity of 165 cps in water and 150 cps in a propylene glycol and water media Both mixtures were hazy, indicating dispersions were obtained The dispersions can be used to make hair styling aids, gels, mousse, hair sprays, because of their superior set retention, holding properties, lubricity, ease of combing, and can be used to make a hair conditioner alone and in a shampoo formulation, since the polymer comes out of the dispersion and deposits on the hair. Because of the low viscosity of aqueous solutions and dispersions formed of the polymers, the polymers are especially useful in hair styling aids such as hair sprays and mousse and to coat rubber products such as synthetic and natural rubber gloves. The polymers can be spread on the skin to form a smooth, nongreasy and soft film. The dispersions can be used for coatings, to improve the brushability of paints, and to enhance the lubricity and flow of aqueous media, and for delivery of compounds for cosmetic, medical, and industrial applications. Because of the dispersion-forming properties of these high slip and water absoφtive polymers comprising about 0 1% to about 15% of polydimethylsiloxane polyoxyethylene coopolymers and about 0 01% to about 0 20% water these polymers can be dispersed in water without any solvent and coated onto metals, plastics, and rubber goods. For example an about 3% solvent-free aqueous dispersion of the polymer described in Example 44 and 1.5% molecular sieve filler was used to coat rubber gloves and improve their dry and wet donnability. The combination of filler and the polymer of this aspect absorbs moisture at low and high humidities, enhances the rate of donning, and feels lubricious. Preferably, the amount of polymer in the coating system is from 0.1% to about 10%, preferably from about 0.2% to about 5%, and the amount of filler is from about 0.5% to about 50%, preferably from about 1% to about 30%. Spreading a 0.1% to about 10% solution, lotion and cream of the polymer formed with polydimethysiloxane polyoxyethylene copolymers and 0.01% of about 0.20% on the hands and skin further enhances the donnability of rubber gloves and other rubber products. The polymers of this aspect have viscosities at 3% concentration in a 60/40 propylene glycol/water solution of about 1 cps to over 2,000,000 cps, preferably from about 2 cps to about 100,000 cps, more preferably from about 4 cps to about 50,000 cps and most preferably from about 5 cps to about 40,000 cps. The polymer is insoluble at 3% concentration in 60/40 propylene glycol water. The concentration of the polymer capable of forming a solution varies depending on the weight average molecular weight of the polymer and the viscosity of the polymer in aqueous media depends upon polymer variables such as the amount of urea groups and amount and type of diol used in forming the polymer. The polymers comprising silicone-containing diols impart superior wetting, donnability, emolliency, lubricity, flow and water repellency properties, and polymers comprising polyetheφolycarbonate diol, preferably PCD comprising hexane diol, impart spreadability, emulsifying properties, donnability, emolliency, clarity, flow, and water-repellency. The amphiphilic polymers of this aspect formed with the controlled amounts of hydrophilic and hydrophobic polyoxyalkylene diols and very low controlled amounts of water provide coatings, lotions, creams, gels, foams, dispersions, emulsions, and solutions that spread readily over many types of surfaces, including skin, metals, glass, plastics, and elastomers to form soft, hypoallergenic, biocompatible, breathable, non-greasy, protective, and water-resistant films. Because the films have this improved combination of properties, -soft, breathable, water-resistant, infection barrier, and protective, the polymers are useful for cosmetic, industrial and medical applications, such as coatings of catheters, guidewires, and blood collection units.. The creams and lotions containing polymers comprising hydrophobic diols in combination with high and low molecular weight hydrophilic PED can be used in skin care products including but not limited to body lotions, base creams, make-up, sunscreen creams, sunburn lotions, lip stick, nail polish, face and body creams, and the like. The high oxygen transmission rates and softness of these films aid in healing sunburns, cuts and wounds and maintaining a healthy skin. The polymers can be granulated and pulverized to a powder. A solution of the polymer in water is made by mixing the polymer in water at room temperature and then warming the solution, if needed at about 50°C to about 80°C. Finer particle size and higher temperatures in closed agitated vessels shorten the time for solution. The concentration of the polymer in the solution will be from about 0.1% to about 10%, preferably from about 0.5% to about 8%, more preferably from about 1% to about 6%. To the solution can be added oils, waxes, fragrance, emulsifiers, humectant such as propylene glycol and glycerine, desiccants, high molecular weight alcohols, small amounts of ethanol and isopropanol, alpha-hydroxy acids, preservatives, base, perfume, antibactericides, vitamins, herbs, antifungicides, pain-killers and drugs. The mixture is heated at about 50°C to about 80°C for about one minute to several hours to dissolve the ingredients. Ingredients can added at about 25°C to about 40°C to prevent degradation of the additive. An amount of a base selected from , for example, ammonium hydroxide, sodium hydroxide, triethanolamine, aminomethylpropanol, potassium hydroxide, and the like may be added to adjust the pH to the desired value, and to thicken the mixture. Solutions, lotions, emulsions, foams, creams, gels of the polymer of this aspect have a concentration of about 0.01% to about 15% of the polymer, preferably from about 0.1% to about 10% of the polymer. For use in creams, lotions, barrier solutions, and antiperspirants, hair shampoos and conditioners, gel, mousse, bath products, drug and fragrance delivery systems, deodorants, medical and therapeutic mixtures, to aid in donnability of elastomeric gloves, and as thickeners, the amount of polymer is from about 0.1% to about 6%. For amorphous gels, the amount of polymer is from about 1% to about 10%. A stiff gel can be formed of an amount of polymer from about 5% to about 25%. The stiff gels can be used in cosmetic, medical, and industrial applications.

Creams can be made with the magnesium salt of the half ester of succinic acid and propoxylated fatty alcohols. Calcium, zinc, aluminum, and magnesium lanolate and lanolin alcohol are also useful in making creams. It will be appreciated that the typical ingredients of cream, lotion, and solution formulations that are known in the art can be used with the amphiphilic polyether polyurethane of this aspect of the invention. Typical formulations are given in the examples. The creams and lotions can be used to aid in the healing of wounds, damp donnabiliity of gloves, male and female shaving comfort, lubricity, smoothness, fragrance retention, pre- and post-shaving preparations, and, decreasing wrinkles, in flattening scars, and healing scars and reducing their hardness, and can be rubbed on the chest to aid in respiratory illnesses, on fingers and feet to keep them warm during cold weather, under the nose to aid in breathing during respiratory illnesses, on the head to promote a healthy scalp, and on skin to retain sunscreen lotions and creams for longer periods. The films can lengthen the useful period for UV stabilizers, antioxidants, drugs, herbs, vitamins, and reduce the loss through solution in water of drugs, vitamins, and fragrance. The creams and lotions can be used to aid in damp donnability of rubber gloves by absorbing moisture, and improving slip, over small cuts and wounds in combination with a gauze to provide an hypoallergenic, biocompatible, infection barrier, breathable, water-resistant film which promotes the healing of cuts and wounds. Gels using the amphiphilic polyether polyurethanes of the fifth aspect can be used in deodorant sticks and antiperspirants, and to provide a healing environment for burns and wounds. The gels can be spread onto a variety of surfaces including skin, metals, glass, and plastic. The films can aid in acceleration of healing of wounds and cuts in combination with gels and bandages by preventing infection while they allow for the transmission of moisture and oxygen which promote healing, and slow absorption of drugs into the skin. The rate can be accelerated by iontophoresis methods. The films can protect fragile skin from aggressive adhesives. The films can serve to provide a soft low wrinkle feeling to skin. The water-resistant films can retain UV additives for longer periods, and resist rinsing with water. The films can be used to prevent and heal urinary and baby rash, since the films protect the skin and form water-resistant, hypoallergenic, breathable, non-greasy, bacteria and infection barrier. Water-soluble vitamins, hydrophobic materials, growth factors, endothilializers, wound and skin healing molecules drugs, fragrances, perfumes, antibactericides, disinfectants can be added to the solutions, lotions, and creams for use in industrial, medical and skin care creams and lotions. For certain applications such as to encapsulate fragrances and drugs, high viscosity hydrophilic polymers are preferred, such as those that are insoluble in propylene glycol/water, and for other applications water soluble polymers may be preferred. The degree of water solubility can be adjusted by the amount and type of hydrophobic diol, ratio of isocyanate to hydroxyl groups, the amount of urea groups, and the molecular weight used in the reaction mixture for forming the polymer. Also, the degree of hydrophobicity can regulate the rate of leaching of the water-soluble compound. A catheter can be formed from polymers of the second aspects of the present invention which can be coextruded with more hydrophilic polymers described in the third and fourth aspects of this disclosure, depending upon the degree and rate of softening required for the catheter. The coextruded film can range in thickness from about .0001 mil to about 0.050 mil. To obtain a tough highly biocompatible catheter with improved slip properties, the polymers of the fourth and fifth aspects can be coextruded over the polymers of the first and second aspects. The high dry and wet strength polymers of the first and second aspects form the core, while the those of the fourth and fifth apsects provide high slip, low cell adhesion and biocompatibility. The polymers of the second aspect can be coated over those of the fourth and fifth aspects to decrease the elution rates in aqueous media of drugs, chemicals, enzymes, cells, proteins and the like contained in the more hydrophilic polymers. For example, a protein absorbed in the hydrophilic polymer eluted within two weeks and eluted after four weeks when coated with a hydrophobic coating.
