Patent number: 8933139Abstract: Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.Type: GrantFiled: February 26, 2010Date of Patent: January 13, 2015Assignee: Peterson Chemical Technology, Inc.Inventors: Bruce W.

Patent number: 5741823Abstract: The present invention is directed to producing a smooth hard coating on a wood substrate. A layer of a foamed polymerized latex emulsion is applied on the surface of a wood substrate, such as an oriented strand board. The layer is dried, crushed and then cured to form the coating. If desired the cured coating may be provided with a post cure heat treatment to improve its hardness. The present invention is also directed to applying and drying the layer of the foamed polymerized latex emulsion on a mat of wood fibers or flakes and then crushing and curing the crushed layer and the mat into a hardboard having a smooth hard coating. The coating of the present invention is useful as a sealer coat on a wood substrate. By adding pigment to polymerized emulsion, the sealer coat can be used to provide a finish coat on the wood substrate.Type: GrantFiled: August 27, 1996Date of Patent: April 21, 1998Assignee: Rohm and Haas CompanyInventor: Oscar Hsien-Hsiang Hsu

Patent number: 5612385Abstract: Novel aerated fibrous slurry comprising fibrous material, foaming agent, stabilizer, water and gas, which when dried to a water content of not more than 10% by weight, forms a dry, resilient fibrous foam composition. The dry, resilient fibrous foam composition is useful as an inexpensive cushioning filler, as a heat insulating material and as an absorbent of liquids.Type: GrantFiled: August 30, 1994Date of Patent: March 18, 1997Inventors: Anthony Ceaser, Mark A.

Patent number: 5521253Abstract: This invention relates to polymer particles that are acid-free in the swellable polymer core and to hollow polymer particles derived therefrom, and to a process for the production of these particles. The acid-free core advantageously decreases the polymer particle's affinity to water. Applicants have discovered that non-carboxylated latexes having a variety of Tg's will swell at temperatures higher than the Tg of the polymer. These latex particles are useful as opacifying plastic pigments for various coatings and particularly as gloss-enhancing plastic pigments for paper and paperboard coatings. Preparation of the hollow polymer particle comprises the use of (meth)acrylate ester monomers, vinyl esters of carboxylic acids or a mixture thereof which are hydrolyzable and swellable at higher temperatures in alkaline environments. The particles may be encapsulated with a hard shell.Type: GrantFiled: January 19, 1995Date of Patent: May 28, 1996Assignee: The Dow Chemical CompanyInventors: Do I. Lee, Michael R. Mulders, Dwayne J.

Patent number: 5434194Abstract: A method for making a cellular rubber is described, in which water is added to a high water absorption resin, followed by allowing the resulting mixture to stand and form a hydrous gel. The hydrous gel, with or without a foaming agent, is added to a rubber compound and subjected to foaming under conditions sufficient for vulcanization thereby obtaining a cellular rubber having a closed cell structure. Cosmetic puffs using the cellular rubber are also described.Type: GrantFiled: March 29, 1993Date of Patent: July 18, 1995Assignee: Nishikawa Rubber Co., Ltd.Inventors: Satoshi Fujimoto, Masafumi Sugiyama
