Patent number: 6127508Abstract: An epoxy resin composition containing a) an epoxy resin and b) a liquid amine terminated polyamine curing agent prepared by condensing an aminoalkylpiperazine and a dicarboxylic acid. The epoxy resin composition typically requires less than 35% of solvent to produce a sprayable viscosity. A hydroxy-functional flexibilized resin is also produced by reacting (a) an epoxy resin, (b) a liquid aminoalkylpiperazine-based amine terminated polyamine and (c) a hydroxy-functional amine.Type: GrantFiled: May 20, 1997Date of Patent: October 3, 2000Assignee: Shell Oil CompanyInventors: Larry Steven Corley, Martin L. Ehrlich

Patent number: 6111050Abstract: A fluorine-containing curable composition comprises (A) a linear perfluoro compound having at least two secondary amino groups per molecule and a divalent perfluoroalkylene or divalent perfluoropolyether structure in the main chain, and (B) a crosslinkable fluorinated compound having at least three functional groups which are crosslinkable with the secondary amino groups of (A). This composition readily cures, with standing at room temperature or heating only, to a cured product having excellent solvent and chemical resistance.Type: GrantFiled: September 21, 1998Date of Patent: August 29, 2000Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Kouichi Yamaguchi, Noriyuki Koike, Masatoshi Arai, Hirofumi Kishita

Patent number: 5962093Abstract: A laminate structure comprises one or more layers of an organic polymer and one or more layers of a hydroxy-functionalized polyetheramine, wherein the hydroxy-functionalized polyetheramine layer is adhered directly to a contiguous organic polymer layer without an adhesive layer therebetween. The hydroxy-functionalized polyetheramine is prepared by reacting (1) a difunctional amine with (2) a diglycidyl ether or a diepoxy-functionalized poly(alkylene oxide) under conditions sufficient to cause the amine moieties to react with the epoxy moieties to form a polymer backbone having amine linkages, ether linkages and pendant hydroxyl moieties and then treating the reaction product with a monofunctional nucleophile which is not a primary or secondary amine.Type: GrantFiled: October 22, 1997Date of Patent: October 5, 1999Assignee: The Dow Chemical CompanyInventors: Jerry E. White, Joe T. Sanford, Terry W. Glass
