    Abstract: An epoxy terminated prepolymer formed as a reaction product of a cycloaliphatic epoxide resin and an amine terminated polymeric polyol, and a catalyst that promotes the reaction of the cycloaliphatic epoxide resin and the aminated polyol. The epoxy terminated prepolymer and an anhydride hardener react to form an epoxy elastomer composition having a microphase separated morphology of hard particles, formed with the anhydride hardener reacted with the epoxy terminated prepolymer, dispersed in a soft continuous phase formed from polymeric polyol in the epoxy terminated prepolymer.

    Abstract: A polyisocyanate component, a polyurethane foaming system, and an article made therefrom, wherein the polyisocyanate component includes (a) a preformed mixture including an aromatic oxazolidone compound that is the reaction product of at least one aromatic epoxide and at least one first polyisocyanate having an average isocyanate functionality of no more than 2.7 and greater than 1.8, in the presence of at least one catalyst, the aromatic oxazolidone compound includes at least one free isocyanate group and at least one aromatic oxazolidone group, the aromatic oxazolidone group includes an aromatic group and an oxazolidone group, and (b) at least one second polyisocyanate has an average isocyanate functionality equal to or greater than 2.7 and less than 6.0. The second polyisocyanate is added to the preformed mixture to form the polyisocyanate component. The polyisocyanate component has a viscosity of no more than 4.0 Pa-sat 25° C., an aromatic oxazolidone group content of 2 weight percent to 10 weight percent based on a total weight of the polyisocyanate component, and an average isocyanate functionality of from 1.8 to 6.0.

    Abstract: An epoxy composition that includes an epoxy-terminated prepolymer, an alkanolamine hardener having at least one hydroxyl group and an organometallic compound, where amine groups of the alkanolamine hardener react with epoxy groups of the epoxy-terminated prepolymer in a stoichiometric ratio to form a cured epoxy composition. The epoxy-terminated prepolymer is formed from a reaction product of an amine terminated polymeric polyol and a molar excess of epoxy groups in an epoxy monomer, relative to a molar amount of amine groups in the amine terminated polymeric polyol.
