Title: Blends of polymers, particularly polycarbonates, acrylate-modified rubber compositions and additional polyacrylates
Inventor: ZIMMERMAN DANIEL D
IPC: C08L51/06
Filed: 1990-05-02
Abstract: ?0,622 BLENDS OF POLYMERS, PARTICULARLY POLYCARBONATES, ACRYLATE-MODIFIED FUBBER COMPOSITIONS AND ADDITIONAL POLYACRYLATES     ABSTRACT      The modified  rubber compositions comprise by weight about 15-60% of a highly saturated aliphatic rubber such as ethylene-propylene-diene rubber, about 25-80% of preferably non-nitrogenous acrylate monomer units; and less than about 5% multi-functional monomer units.  The compositions exist as amorphous heterogeneously dispersed phases.  The first phase comprises the copolymer rubber to which polymers of at least 10%, preferably 20%, and more preferably 30% of the other monomer units are grafted.  The second phase comprises the other monomers polymerized as homo and copolymers, not grafted to the rubber.  Greater than 10% and preferably 20% of the monomer units other than rubber are grafted to the rubber.  The number average molecular weight of the grafts is between 10,000 and 80,000 daltons.     The modified rubber composition, additional, preferably non-nitrogenous, polyacrylate polymer, and another polymer are mixed together to form a polymer blend having higher impact strength and other important properties.  The other polymers  are often more expensive and usually have  some advantageous property compared to polyacrylate.  Other poly-mers disclosed are: polycarbonates, SAN, polystyrene, poly-vinylchloride,  polypropylene,  polyester,  styrene  maleic anhydride, chlorinated polyethylene, polyethylene terephtha-late, nylon and ABS.  Polycarbonate blends preferably com-prise a total of at least 35% and up to 65% polyacrylate.     The proportion of rubber used to form the graft rubber com-position to the total graft rubber composition and poly-acrylate polymer in polycarbonate blends is in the range of approximately 2 to less than 30% by weight and preferably no greater than 25%.      The modified rubber composition is present in polycar-bonate blends in the range of approximately 6% to 50% by weight.  The added polyacrylate preferably has a molecular weight greater than 80,000 daltons.

Title: R-enzyme-treated breakfast cereal and preparation process
Inventor: ANTRIM RICHARD L
IPC: A23L7/104
Filed: 1990-05-16
Abstract: ABSTRACT OF THE DISCLOSURE      A process of preparing a shredded wheat product.  The process includes cooking whole wheat berries with water to at least partially gelatinize the wheat starch.  The bran layer of the whole wheat berries is intact and does not have any penetrations therein before the cooking begins.  The cooked wheat berries are treated with an R-enzyme.  The treated, cooked wheat berries are tempered for a sufficient period of time to retrograde a substantial portion of the starch in the berries.  The process allows the use of a tempering time which is much less than the tempering period in the conventional or commercial process of preparing shredded wheat.  The tempered wheat berries are formed into a shredded form and then baked or toasted.

Title: Disposable syringe for once-only use
Inventor: LO DUCA CARMELO
IPC: A61M5/50
Filed: 1990-06-21
Abstract: Abstract:            DISPOSABLE SYRINGE FOR ONCE-ONLY USE       This invention relates to a disposable syringe for once-only use. The syringe comprises a hollow cylinder which carries a needle at one end and houses a plunger connected to one end of a shaft, the other end of which is provided with a manually operable shaped head.  The diameter of this head is a maximum in proximity to that portion adjacent to the shaft and reduces gradually towards the free end of the head.  The shaft length is such that when the plunger has been pushed to the bottom of the cylinder, the maximum diameter protion of the head is housed within the cavity of the cylinder, from which the decreasing diameter portion of the head projects, so that the shaft head can no longer be gripped by the fingers in order to move the shaft backwards and reuse the syringe.

Title: Removal of acidic contaminants from tertiary butyl hydroperoxide
Inventor: MARQUIS EDWARD T
IPC: C07C407/00
Filed: 1990-08-29
Abstract: REMOVAL OF ACIDIC CONTAMINANTS FROM TERTIARY BUTYL HYDROPEROXIDE        (Docket No. 80,817-F) ABSTRACT OF THE DISCLOSURE    The distillation product fraction obtained from an isobutane oxidation reaction product after the removal of unreacted isobutane will contain tertiary butyl hydroperox-ide, tertiary butyl alcohol and carboxylic acid contaminants such as formic acid, acetic acid and isobutyric acid.  It has been discovered that when the distillation product frac-tion is treated with about 1/2 to 1 equivalents of calcium oxide and/or calcium hydroxide based on the carboxylic acid content of the distillate product fraction, a portion of the carboxylic acid contaminants will precipitate thus partially purifying the distillation product fraction so that, there-after, molybdenum precipitation will be substantially inhibited when the thus-treated distillation product frac-tion is used as a feedstock for an epoxidation reaction wherein tertiary butyl hydroperoxide is reacted with an olefin in the presence of a soluble molybdenum catalyst to provide an olefin epoxide and additional tertiary butyl hydroperoxide.

Title: Aqueous adhesive solutions without solvent
Inventor: ENGMANN LOTHAR
IPC: C09J129/10
Filed: 1991-07-29
Abstract: (J/su) UHU GmbH, B?hl, Baden Abstract The invention provides novel aqueous adhesive solutions which do not contain any organic solvent. These solutions are entirely clear and show the perceptible tackiness desired by the consumer.        The solutions contain mixed polymers comprising acrylic acid, vinyl acetate and a monomeric surfactant copolymerisable therewith which is selected from certain types of compounds as effective adhesive components. One of the selected types of compounds is a polyoxyethylene-allyl alcohol (polyoxyethylene glycol allyl ether) of the formula IA below   (IA) or its methyl ether of the formula IB below                   (IB) where n = 2 to 50.        The adhesive solutions  can be prepared in  a simple manner by initially introducing an aqueous solu-tion of a surfactant and metering in the acrylic acid partially neutralised with NaOH in the form of an aqueous solution and the vinyl acetate and, if desired, a further ethylenically unsaturated comonomer over a period of several hours. The reaction is advantageously carried out at temperatures in the range from 70 to 85°C. In the case of  higher  monomer  concentrations,  molecular  weight regulators, such as polyglycols and/or acetates thereof, can additionally be used in the reaction batch. In this manner, the solids content of the adhesive solution can be adjusted to the desired value in a simple manner.
