Publication number: 20100264365Abstract: The present invention relates to a novel method for compatibilizing, i.e. improving miscibility of, otherwise immiscible organic materials highly useful in the fibers industry, as well as the compatibilized product of the method. These compatibilized products are stable in the liquid phase at temperatures ranging from about 40° C. to about 200° C. The method involves use of a glycol derived from polymerization of alkylene oxide and tetrahydrofuran, the alkylene oxide having from 2 to 4 carbon atoms, i.e. poly(tetramethylene-co-alkyleneether) glycol, in the mixture.Type: ApplicationFiled: April 15, 2009Publication date: October 21, 2010Applicant: INVISTA NORTH AMERICA S.A.R.L.Inventors: QUN SUN, Edwin L.

Patent number: 7732646Abstract: An allyl type crosslinking agent for use in production of a super water-absorbent polymer comprising a polymerizable compound having a carbon-carbon double bond or a salt thereof. The crosslinking agent comprises a linear hydroxypolyallyl ether having at least one hydroxyl group and at least two allyl groups obtained by allyletherification of hydroxyl groups in a linear polyol compound selected from the group consisting of erythritol, xylitol and sorbitol. This allyl type crosslinking agent is highly soluble in an aqueous solvent, and can give an excellent super water-absorbent polymer, which cannot be obtained in the prior arts, having high levels of both of water absorptivity under atmospheric pressure and water absorptivity under pressurized conditions.Type: GrantFiled: January 3, 2005Date of Patent: June 8, 2010Assignee: Daiso Co., Ltd.Inventors: Shin-ichiro Nakamura, Yasumi Shimizu, Tohru Matsutomi, Thomas Daniel

Patent number: 7670501Abstract: Microcellular polyurethane flexible foams having densities no greater than 0.3 g/cc which are suitable for use as lightweight shoe sole components are produced with carbon dioxide in an amount such that the polyurethane-forming mixture has a free rise density of from about 0.03 to about 0.3 g/cc. At least a portion of that carbon dioxide is dissolved as a gas into one or both of the reaction components. The amount of dissolved carbon dioxide must be such that the froth density of the isocyanate and/or isocyanate-reactive component(s) in which the carbon dioxide is dissolved will be from about 0.1 to about 0.8 g/cc. Additional carbon dioxide may be formed by the reaction of water and isocyanate during the polyurethane-forming reaction but the total amount of CO2 present should be controlled to ensure that the polyurethane-forming mixture has a free rise density of from about 0.03 to 0.3 g/cc.Type: GrantFiled: May 27, 2005Date of Patent: March 2, 2010Assignee: Bayer MaterialScience LLCInventors: Usama E.
