DEFINITION

Classification: 523/403

Two or more polymers containing more than one 1,2-epoxy group, two or more polymers derived from reactants containing more than one 1,2-epoxy group, or combination thereof or one of said polymers and a reactant containing at least one 1,2-epoxy group:

(under subclass 402) Subject matter wherein the composition contains two or more polymers each containing more than one 1,2-epoxy group, two or more polymers derived from reactants containing more than one 1,2-epoxy group, or combination thereof; or one of said polymers admixed with a reactant containing at least one 1,2-epoxy group, e.g., a mixture of the polyglycidyl ether of bisphenol A diglycidyl ether admixed either with an epoxidized soybean oil or epichlorohydrin, etc.

(1) Note. For purposes of classification, an epoxidized soybean oil or other unsaturated triglycerides will be assumed as plural epoxy materials.
