  • Publication number: 20100264365
    Abstract: 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.

  • Patent number: 7732646
    Abstract: 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.

  • Patent number: 7670501
    Abstract: 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.

  • Publication number: 20090281214
    Abstract: Disclosed are plasticizer compositions including cyclodextrin derivatives, a flexible PVC composition with suppression of the migration of a plasticizer containing the same, and a manufacturing method thereof. The manufacturing method of the flexible PVC composition of the present invention includes steps of (S1) preparing cyclodextrin derivatives; (S2) mixing the cyclodextrin derivatives, PVC and a low molecular weight liquid plasticizer to form a plastisol; and (S3) heating the plastisol to form a solution and cooling the solution. The manufacturing method of the present invention may be useful to mass-produce flexible PVC with suppression of the migration of a plasticizer in a simple and economic manner without using solvents since the cyclodextrin derivatives are used as a compound that can suppress the migration of a plasticizer The flexible PVC has an effect of reducing an amount of the migrated plasticizer without deterioration in its physical properties.
