BACKGROUND OF THE INVENTION
Homopolymers based on 2,5-furandicarboxylic acid or an ester thereof and 1,4-cyclohexanedimethanol are known in the art.
SUMMARY OF THE INVENTION
It is believed that certain copolyester compositions made from 2,5-furandicarboxylic acid, an ester thereof, or mixtures thereof, and 1,4-cyclohexanedimethanol are superior to polyesters known in the art with respect to stable glass transition temperatures.

DETAILED DESCRIPTION OF THE INVENTION
The present invention may be understood more readily by reference to the following detailed description of certain embodiments of the invention and the working examples. In accordance with the purpose(s) of this invention, certain embodiments of the invention are described in the Summary of the Invention and are further described herein below. Also, other embodiments of the invention are described herein.
Copolyesters synthesized from 2,5-furandicarboxylic acid (FDCA) or its derivatives with 1,4-cyclohexanedimethanol (CHDM) have an advantage of nearly constant glass transition temperature (Tg) over a wide range of compositions, compared to commercial terephthalic acid-based copolyesters (PET, PETG, PCTG, PCT), for which Tg varies measurably as composition varies. This advantage may be beneficial for producing copolyesters with constant Tg even if composition varies during manufacturing.
The term “polyester”, as used herein, is intended to include “copolyesters” and is understood to mean a synthetic polymer prepared by the reaction of one or more difunctional carboxylic acids and/or multifunctional carboxylic acids with one or more difunctional hydroxyl compounds and/or multifunctional hydroxyl compounds. Typically the difunctional carboxylic acid can be a dicarboxylic acid and the difunctional hydroxyl compound can be a dihydric alcohol such as, for example, glycols and diols. The term “glycol” as used in this application includes, but is not limited to, diols, glycols, and/or multifunctional hydroxyl compounds, for example, branching agents. Alternatively, a difunctional carboxylic acid may be a hydroxy carboxylic acid such as, for example, p-hydroxybenzoic acid, and the difunctional hydroxyl compound may be an aromatic nucleus bearing 2 hydroxyl substituents such as, for example, hydroquinone. The term “residue”, as used herein, means any organic structure incorporated into a polymer through a polycondensation and/or an esterification reaction from the corresponding monomer. The term “repeating unit”, as used herein, means an organic structure having a dicarboxylic acid residue and a diol residue. Thus, for example, the dicarboxylic acid residues may be derived from a dicarboxylic acid monomer or its associated acid halides, esters, salts, anhydrides, or mixtures thereof. As used herein, therefore, the term dicarboxylic acid is intended to include dicarboxylic acids and any derivative of a dicarboxylic acid, including its associated acid halides, esters, half-esters, salts, half-salts, anhydrides, mixed anhydrides, or mixtures thereof, useful in a reaction process with a diol to make polyester. Furthermore, as used in this application, the term “diacid” includes multifunctional acids, for example, branching agents. As used herein, the term “terephthalic acid” is intended to include terephthalic acid itself and residues thereof as well as any derivative of terephthalic acid, including its associated acid halides, esters, half-esters, salts, half-salts, anhydrides, mixed anhydrides, or mixtures thereof or residues thereof useful in a reaction process with a diol to make polyester.
In one embodiment, furandicarboxylic acid and/or its ester may be used as a starting material. In yet another embodiment, mixtures of 2,5-furandicarboxylic acid and its ester may be used as the starting material and/or as an intermediate material.
Terephthalic acid and/or its ester may also be used in one embodiment as one of the starting materials, with 2,5-furandicarboxylic acid and/or its ester. In another embodiment, dimethyl terephthalate may be used instead of terephthalic acid as a starting material. In yet another embodiment, mixtures of terephthalic acid and dimethyl terephthalate may be used as starting materials and/or as an intermediate material.
Isophthalic acid and/or its ester may also be used in one embodiment as one of the starting materials, with 2,5-furandicarboxylic acid and/or its ester.
In another embodiment, terephthalic acid and/or its ester as well as isophthalic acid and/or its ester may also be used in combination as starting materials, with 2,5-furandicarboxylic acid and/or its ester.
The polyesters used in the present invention typically can be prepared from dicarboxylic acids and diols which react in substantially equal proportions and are incorporated into the polyester polymer as their corresponding residues. The polyesters of the present invention, therefore, can contain substantially equal molar proportions of acid residues (100 mole %) and diol (and/or multifunctional hydroxyl compounds) residues (100 mole %) such that the total moles of repeating units is equal to 100 mole %. The mole percentages provided in the present disclosure, therefore, may be based on the total moles of acid residues, the total moles of diol residues, or the total moles of repeating units. For example, a polyester containing 30 mole % isophthalic acid, based on the total acid residues, means the polyester contains 30 mole % isophthalic acid residues out of a total of 100 mole % acid residues. Thus, there are 30 moles of isophthalic acid residues among every 100 moles of acid residues. In another example, a polyester containing 30 mole % 1,4-cyclohexanedimethanol, based on the total diol residues, means the polyester contains 30 mole 1,4-cyclohexanedimethanol residues out of a total of 100 mole % diol residues.

Suitable catalysts for use in this process include, but are not limited to, organo-zinc or tin compounds, including but not limited to, zinc acetate, butyltin tris-2-ethylhexanoate, dibutyltin diacetate, and/or dibutyltin oxide. Other catalysts may include, but are not limited to, those based on titanium, zinc, manganese, lithium, germanium, and cobalt. A phosphorus compound may be used in connection with this invention. In one embodiment, the catalyst can be a combination of manganese, cobalt and germanium which can be used with phosphorus compounds as described herein. In another embodiment, titanium and manganese can be used. In one embodiment, tetrabutyl titanate can be used in combination with manganese acetate. In one embodiment, titanium and tin catalysts can be combined. In one embodiment, tin can be used as the only catalyst. In one embodiment, titanium can be used as the only catalyst. The invention further relates to a polyester product made by the process described above.
The invention further relates to a polymer blend. The blend comprises:
(a) 0.01 to 99.99 weight % of at least one of the polyesters described above; and
(b) 0.01 to 99.995 weight % of at least one of the polymeric components.
Suitable examples of the polymeric components include, but are not limited to, nylon, other polyesters different from those described herien, nylon, polyamides such as ZYTEL® from DuPont; polyesters different from those described herein; polystyrene, polystyrene copolymers, styrene acrylonitrile copolymers, acrylonitrile butadiene styrene copolymers, poly(methylmethacrylate), acrylic copolymers, poly(ether-imides) such as ULTEM® (a poly(ether-imide) from General Electric); polyphenylene oxides such as poly(2,6-dimethylphenylene oxide) or poly(phenylene oxide)/polystyrene blends such as NORYL 1000® (a blend of poly(2,6-dimethylphenylene oxide) and polystyrene resins from General Electric); other polyesters; polyphenylene sulfides; polyphenylene sulfide/sulfones; poly(ester-carbonates); polycarbonates such as LEXAN® (a polycarbonate from General Electric); polysulfones; polysulfone ethers; and poly(ether-ketones) of aromatic dihydroxy compounds or mixtures of any of the other foregoing polymers. The blends can be prepared by conventional processing techniques known in the art, such as melt blending or solution blending.
The polyesters according to the invention can also be used in blends, such blends being obtainable by means of reactive extrusion too, with polymers of natural origin, such as starch, cellulose, chitin and chitosan, alginates, proteins such as gluten, zein, casein, collagen, gelatine, natural rubbers, rosinic acid and its derivatives, lignins and their derivatives, natural fibers (such as for example jute, kenaf, hemp). The starches and celluloses may be modified and may include, for instance, the starch and cellulose esters with a degree of substitution coming between 0.2 and 2.5, hydroxypropylated starches, and modified starches with fatty chains. Starch can also be used in either destructurized or gelatinised form, or as a filler. The starch may represent the continuous or the dispersed phase, or it may be in co-continuous form. In the case of dispersed starch, the starch particles can have mean dimension of less than 1μ, or less than 0.5μ.
With regard to the starch particles dimension, these are measured in the transverse direction with respect to the direction of the extrusion flow or, anyhow, with respect to the direction of the material's output. The dimension of a starch particle is therefore measured on the bidimensional shape resulting from the transverse direction. The mean dimension is calculated as the numeral (or arithmetic) average of the particle diameters.
In case of a spherical particle the particle diameter corresponds to the diameter of the smaller circle in which the particle can be inscribed.
In case of a non-spherical particle the particle diameter (d) is calculated according to the following formula:

d=√d1d2

where d1 is the minor diameter and d2 is the major diameter of the ellipse in which the particle can be inscribed or approximated.
Mixtures of polyesters according to the invention wherein starch represents the dispersed phase can form biodegradable polymeric compositions with good-resistance to ageing and to humidity. Indeed, these polymeric compositions can maintain a high tear strength even in condition of low humidity.
Such characteristics can be achieved when the water content of the composition during mixing of the component is kept between 1% and 15% by weight. It is, however, also possible to operate with a content of less than 1% by weight, in this case, starting with predried and pre-plasticized starch.
It could be useful also to degrade starch at a low molecular weight before or during compounding with the polyesters of the present invention in order to have in the final material or finished product a starch inherent viscosity between 1 and 0.2 dl/g, or between 0.6 and 0.25 dl/g, or between 0.55 and 0.3 dl/g.
Desctructurized starch can be obtained before or during mixing with the polyesters according to the present invention in presence of plasticizers such as water, glycerol, di and poly glycerols, ethylene or propylene glycol, ethylene and propylene diglycol, polyethylene glycol, polypropylenglycol, 1,2 propandiol, trymethylol ethane, trymethylol propane, pentaerytritol, dipentaerytritol, sorbitol, erytritol, xylitol, mannitol, sucrose, 1,3 propanediol, 1,2 butanediol, 1,3 butanediol, 1,4 butanediol, 1,5 pentanediol, 1,5 hexanediol, 1,6 hexanediol, 1,2,6 hexanetriol, 1,3,5 hexanetriol, neopentyl glycol and polyvinyl alcohol prepolymers and polymers, polyols acetates, ehtoxylates and propoxylates, particularly sorbitol ethoxylate, sorbitol acetate, and pentaerythritol acetate. The quantity of high boiling point plasticizers (plasticizers different from water) used are generally from 0% to 50%, or from 10% to 30% by weight, relative to the starch.
Water can be used as a plasticizer in combination with high boiling point plasticizers or alone during the plastification phase of starch before or during the mixing of the composition and can be removed at the needed level by degassing on one or more steps during extrusion. Upon completion of the plastification and mixing of the components, the water is removed by degassing to give a final content of about 0.2-3% by weight.
Water, as well as high-boiling point plasticizers, modifies the viscosity of the starch phase and affects the rheological properties of the starch/polymer system, helping to determine the dimensions of the dispersed particles. Compatibilizers can be also added to the mixture. They can belong to the following classes:
Additives such as esters which have hydrophilic/lipophilic balance index values (HLB) greater than 8 and which are obtained from polyols and from mono or polycarboxylic acids with dissociation constants pK lower than 4,5 (the value relates to pK of the first carboxyl group in the case of polycarboxylic acids);
Esters with HLB values of between 5,5 and 8, obtained from polyols and from mono or polycarboxylic acids with less than 12 carbon atoms and with pK values greater than 4.5 (this value relates to the pK of the first carboxylic group in the case of polycarboxylic acids);
Esters with HLB values lower than 5.5 obtained from polyols and from fatty acids with 12-22 carbon atoms.
These compatibilizers can be used in quantities of from 0.2 to 40% weight and or from 1 to 20% by weight related to the starch. The starch blends can also contain polymeric compatibilizing agents having two components: one compatible or soluble with starch and a second one soluble or compatible with the polyester.
Examples are starch/polyester copolymers through transesterification catalysts. Such polymers can be generated through reactive blending during compounding or can be produced in a separate process and then added during extrusion, In general block copolymers of an hydrophilic and an hydrophobic units are particularly suitable. Additives such as di and polyepoxides, di and poly isocyanates, isocyanurates, polycarbodiimmides and peroxides can also be added. They can work as stabilizers as well as chain extenders.
All the products above can help to create the needed microstructure.
The starch/polyester ratio can be comprised in the range 5/95% weight up to 60/40% by weight, or 10/90-45/55% by weight.
In such starch-based blends in combination with the polyesters of the present invention it is possible to add polyolefins, polyvinyl alcohol at high and low hydrolysis degree, ethylene vinylalcohol and ethylene vinylacetate copolymers and their combinations as well as aliphatic polyesters such as polybuthylenesuccinate, polybuthylenesuccinate adipate, polybuthylensuccinate adipate-caprolactate, polybuthylensuccinate-lactate, polycaprolactone polymers and copolymers, PBT, PET, PTT, polyamides, polybuthylen terephthalate adipates with a content of terephthalic acid between 40 and 70% with and without sulfonated groups with or without branches and possibly chain extended with diisocyanates or isocyanurates, polyurethanes, polyamide-urethanes, cellulose and starch esters such as acetate, propionate and butryate with substitution degrees between 1 and 3, or between 1.5 and 2.5, polyhydroxyalkanoates, poly L-lactic acid, poly-D lactic acid and lactides, their mixtures and copolymers.
The starch blends of the polyesters of the present invention can be easily processable in film blowing even at MFI (170° C., 5 kg) of 7 g/10 min. Moreover, they can have impact strength higher than 20 kJ/m2, or higher than 30 kJ/m2′ or higher than 45 kJ/m2 (measured on blown film 30 μm thick at 10° C. and less than 5% relative humidity). Particularly resistant and easily processable compounds contain destructurized starch in combination with the polyesters of the invention and polylactic acid polymers and copolymers with and without additives such as polyepoxides, carbodiimmides and/or peroxides.
The starch-base films can be even transparent in case of nanoparticles of starch with dimensions lower than 500 μm or lower than 300 μm. It is also possible to go from a dispersion of starch in form of droplets to a dispersion in which two co-continuous phases coexist and the blend is characterized for allowing a higher water content during processing.
In general, to obtain co-continuous structures it is possible to work either on the selection of starch with high amylopectine content and/or to add to the starch-polyester compositions block copolymers with hydrophobic and hydrophilic units. Possible examples are polyvinylacetate/polyvinylalcohol and polyester/polyether copolymers in which the block length, the balance between the hydrophilicity and hydrophobicity of the blocks and the quality of compatibilizer used can be suitably changed in order to finely adjust the microstructure of the starch-polyester compositions.
The polymers according to the invention can also be blended with polyolefins, such as polyethylene, polypropylene and their copolymers, polyvinyl alcohol, polyvinyl acetate, polyethyl vinyl acetate and polyethylene vinyl alcohol, polyester urethanes, polyurethanes, polyamides, polyureas and aromatic polyesters of the diacid diol type wherein the aromatic acid is 2.5 furandicarboxylic acid.
The polymers according to the invention can also be used as prepolymers in the production of polyurethanes and polyureas.
In one embodiment, the polyesters of the invention are blended with starch.
The polyesters according to the invention can also be used in blends with polymers of synthetic origin and with the previously-mentioned polymers of natural origin.
Binary and ternary blends of the polyester according to the present invention with biodegradable polyesters of the type disclosed above and/or with polymers of natural origin are particularly suitable for the production of films. Advantageously, the films obtained with said blends show excellent mechanical properties.
In one embodiments, the polyesters of the invention can be mixed with starch and polylactic acid.
Blends of the polyesters according the present invention with PLA are of particular interest because their high compatibility with PLA polymers and copolymers permits to cover materials with a wide range of rigidities—which makes these blends particularly suitable for injection molding and extrusion.
Moreover, blends of such polyesters with poly L-lactic acid and poly D-lactic acid or poly L-lactide and D-lactide where the ratio between poly L- and poly D-lactic acid or lactide is in the range 10/90-90/10, or 20/80-80/20, and the ratio between aliphatic-aromatic polyester and the polylactic acid or PLA blend is in the range 5/95-95/5, or 10/90-90/10, are of particular interest for the high thermal resistance. Polylactic acid or lactide polymers or copolymers are generally of molecular weight Mn in the range between 30,000 and 30,000 or between 50,000 and 250,000.
To improve the transparency and toughness of such blends and decrease or avoid a lamellar structure of polylactide polymers, it is possible to introduce other polymers as compatibilizers or toughening agents such as: polybutylene succinate and copolymers with adipic acid and or lactic acid and or hydroxyl caproic acid, polycaprolactone, aliphatic polymers of diols from C2 to C13 and diacids from C4 to C13, polyhydroxyalkanoates, polyvinylalcohol in the range of hydrolysis degree between 75 and 99% and its copolymers, polyvinylacetate in a range of hydrolysis degree between 0 and 70%, or between 0 and 60%. In one embodiment, the diols used in the polyesters of the invention can be chosen from ethylene glycol, propandiol, butanediol and the acids used in the polyesters of the invention can be chosen from: azelaic, sebacic, undecandioic acid, dodecandioic acid, brassylic acid and their combinations.
To maximize compatibility among the polyesters of the invention and polylactic acid it is very useful the introduction of copolymers with blocks having high affinity for the aliphatic-aromatic copolyesters of the invention, and blocks with affinity for the lactic acid polymers or copolymers. One embodiment of the invention can be block copolymers of the aliphatic aromatic copolymers of the invention with polylactic acid. Such block copolymers can be obtained taking the two original polymers terminated with hydroxyl groups and then reacting such polymers with chain extenders able to react with hydroxyl groups such as diisocyanates.
Examples are 1,6 hexamethylene diisocyanate, isophorone diisocyanate, methylene diphenildiisocyanate, toluene diisocyanate or the like. It is also possible to use chain extenders able to react with carboxylic groups like di and poly epoxides (e.g. bisphenols diglycidyl ethers, glycerol diglycidyl ethers) divinyl derivatives if the polymers of the blend are terminated with acid groups. It is possible also to use as chain extenders carbodiimmides, bis-oxazolines, isocyanurates etc.
The intrinsic viscosity of such block copolymers can be between 0.3 and l=1.5 dl/g, or between 0.45 and 1.2 dl/g. The amount of compatibilizer in the blend of aliphaticaromatic copolyesters and polylactic acid can be in the range between 0.5 and 50% by weight, or between 1 and 30% by weight, or between 2 and 20% by weight.
The polyesters according to the present invention can advantageously be blended also with nucleating agents and filler both of organic and inorganic nature.
Examples of nucleating agents include talc, saccharine sodium salt, calcium silicate, sodium benzoate, calcium titanate, boron nitride, zinc salts, porphyrin, chlorine, phlorin, porphodimethine, porphomethine, bacteriochlorin, isobacteriochorin, porphyrinogen, phorbin, isotactic polypropylene, PLA with low molecular weight and PBT.
In one embodiment, the amount of fillers can be in the range of 0.5-70% by weight, or 5-50% by weight.
As regards organic fillers, wood powder, proteins, cellulose powder, grape residue, bran, maize husks, compost, other natural fibres, cereal grits with and without plasticizers such as polyols can be mentioned.
As regards inorganic fillers, it can be mentioned substances that are able to be dispersed and/or to be reduced in lamellas with submicronic dimensions, for example, less than 500 ntn or less than 300 nm, or less than 50 nm. In one embodiment, inorganic fillers can be selected from zeolites and silicates of various kind such as wollastonites, montmorillonites, hydrotalcites also funetionalised with molecules able to interact with starch and or the specific polyester. The use of such fillers can improve stiffness, water and gas permeability, dimensional stability and maintain transparency.
The biodegradable polyesters according to the invention are biodegradable according to the standard EN 13432.
The process for producing the polyesters according to the present invention can be conducted using any of the known processes according to the state of the art. In particular, the polyesters can be advantageously obtained using a polycondensation reaction. The copolyester polymerisation process can be advantageously conducted in the presence of a suitable catalyst. An example of a suitable catalyst might be the organometallc compounds of tin such as the derivatives of stannoic acid, or the compounds of titanium such as orthobutyl titanate, or the compounds of aluminium such as Al-triisopropyl, or of antimony and zinc.
In addition, the polyester compositions and the polymer blend compositions containing the polyesters useful in this invention may also contain from 0.01 to 25% by weight or 0.01 to 20% by weight or 0.01 to 15% by weight or 0.01 to 10% by weight or 0.01 to 5% by weight of the total weight of the polyester composition of common additives such as colorants, dyes, mold release agents, release agents that release the polymer from rolls of the manufacturing equipment, flame retardants, plasticizers, nucleating agents, stabilizers, including but not limited to, UV stabilizers, thermal stabilizers and/or reaction products thereof, fillers, and impact modifiers. Examples of typical commercially available impact modifiers well known in the art and useful in this invention include, but are not limited to, ethylene/propylene terpolymers; functionalized polyolefins, such as those containing methyl acrylate and/or glycidyl methacrylate; styrene-based block copolymeric impact modifiers; and various acrylic core/shell type impact modifiers. For example, UV additives can be incorporated into articles of manufacture through addition to the bulk, through application of a hard coat, or through coextrusion of a cap layer. Residues of such additives are also contemplated as part of the polyester composition.
In the case of adding release agents which reduce adhesion to manufacturing equipment such as calendering rolls, these can be selected from the group comprising esters of fatty acids and amides, and metal salts, soaps, paraffin, or hydrocarbon waxes such as: zinc stearate, calcium stearate, aluminum stearate, stearamides, erucamides, behenamides, white beeswax, candelilla wax, LDPE with high MFI such as Eastman Epolene N21, Epolene E20, and Lofio HOB 7119.
An increase in the molecular weight of the polyesters can be advantageously obtained, for instance, by adding various organic peroxides during the extrusion process. The increase in the molecular weight of the biodegradable polyesters is easily detectable on observing the increase in the viscosity values after processing the polyesters with the peroxides.
Examples of peroxides that can advantageously be used are selected from the group of dialkyl peroxides, such as: benzoyl peroxide, lauroyl peroxide, isononanoyl peroxide, di-(tbutylperoxyisopropyl)benzene, t-butyl peroxide, dicumyl peroxide, alpha,alpha-di(t-20 butylperoxy)diisopropylbenzene, 2,5-dimethyl-2,5 di(t-butylperoxy)hexane, t-butyl cumyl peroxide, di-t-butylperoxide, 2,5-dimethyl-2,5-di(t-butylperoxy)hex-3-yne, di(4-tbutylcyclohexyl)peroxydi-carbonate, dicetyl peroxydicarbonate, dimyristyl peroxydicarbonate, 3,69-triethyl-3,6,9-trimethyl-1,4,7-triperoxonan, di(2-ethylhexyl)peroxydicarbonate and mixtures thereof.
In one embodiment, peroxides can be added to the polyesters according to the invention in a quantity of less than 0.5% by weight, or less than 0.01-0.2% by weight, or less than 0.01-0.1% by weight.
The polyesters of the invention can comprise at least one chain extender. Suitable chain extenders include, but are not limited to, multifunctional (including, but not limited to, bifunctional) isocyanates, multifunctional epoxides, including for example, epoxylated novolacs, and phenoxy resins. In certain embodiments, chain extenders may be added at the end of the polymerization process or after the polymerization process. If added after the polymerization process, chain extenders can be incorporated by compounding or by addition during conversion processes such as injection molding or extrusion. The amount of chain extender used can vary depending on the specific monomer composition used and the physical properties desired but can be selected from 0.1 percent by weight to about 10 percent by weight, or from 0.1 to about 5 percent by weight, based on the total weight of the polyester.
The polyesters of the invention can contain phosphorous compounds including but not limited to phosphoric acid, phosphorous acid, phosphonic acid, phosphinic acid, phosphonous acid, and various esters and salts thereof. These can be present in the polyester compositions useful in the invention. The esters can be alkyl, branched alkyl, substituted alkyl, difunctional alkyl, alkyl ethers, aryl, and substituted aryl. In one embodiment, the number of ester groups present in the particular phosphorous compound can vary from zero up to the maximum allowable based on the number of hydroxyl groups present on the phosphorus compound used. Examples of phosphorus compounds useful in the invention can include phosphites, phosphates, phosphinates, or phosphonites, including the esters thereof.
The polyesters of the invention can have good molecular weight. In one embodiment, the number average molecular weight of the polyesters is at least 10,000. In one embodiment, the number average molecular weight of the polyesters is at least 20,000.
Reinforcing materials may be useful in the compositions of this invention. The reinforcing materials may include, but are not limited to, carbon filaments, silicates, mica, clay, talc, titanium dioxide, Wollastonite, glass flakes, glass beads and fibers, and polymeric fibers and combinations thereof. In one embodiment, the reinforcing materials are glass, such as, fibrous glass filaments, mixtures of glass and talc, glass and mica, and glass and polymeric fibers.
In another embodiment, the invention further relates to articles of manufacture comprising any of the polyesters and blends described herein.

Example 1
Poly(1,4-cyclohexylenedimethylene furandicarboxylate), PCF
A 100 ml round-bottom flask fitted with a sidearm and condensate collection flask was charged with 0.1 mole FDCA (15.7 g), 0.11 mole CHDM (15.1 g), and a solution of titanium tetraisopropoxide in ethylene glycol such that the concentration of Ti was approximately 50 ppm based upon final polymer weight. The mixture was heated to 200° C. while stirring at atmospheric pressure under a N2 purge until a well-dispersed slurry was obtained. The temperature was then increased to 285° C. over a period of about 15 minutes, at which point a clear liquid melt was observed. The pressure was then slowly reduced to 0.5 Torr by means of a vacuum pump and held for about 60 minutes, collecting condensate in a sidearm flask cooled with dry ice located between the reaction flask and the vacuum pump. The resulting polymer was cooled to room temperature, separated from the flask, and cryogenically ground. The resulting polymer had IhV=0.81 dL/g and Tg=86° C.
Example 2
