DEFINITION

Classification: 523/400

Process of forming a composition containing a nonreactive material (NRM) and a polymer containing more than one 1,2-epoxy group, or a preformed polymer derived from or admixed with a reactant containing more than one 1,2-epoxy group; or with a polymer derived from an epihalohydrin and a

polyhydrin phenol or polyol; or composition or product thereof:

(under subclass 1) Subject matter concerning the process of forming a composition containing a nonreactive material (NRM) admixed with at least one polymer containing more than one 1,2-epoxy group; or with a polymer derived from or admixed with a reactant containing more than one 1,2-epoxy group; or with a polymer derived from an epihalohydrin and a polyhydric phenol or polyol; or composition or product thereof.

(1) Note. Polymers anticipated here would be of the type containing two or more 1,2-epoxy groups, e.g., phenol-formaldehyde resin etherified with epichlorohydrin, polyglycidyl methacrylate, epoxidized polybutadiene, polyglycidyl ethers of bis-phenol diglycidyl ether, or from the reaction of epichlorohydrin with resorcinol or 1,4-dimethylolcyclohexane, etc.

(2) Note. For purposes of classification here epoxidized soybean oil (triglycerides of oleic, linoleic, linolenic acids, etc.) if used as a reactant will be considered as a plural epoxide in view of its inherent plural unsaturation. Likewise, the epoxidation of other plural unsaturated materials, e.g., polybutadiene, in the absence of disclosure to the contrary, will produce a plural epoxide reactant.

(3) Note. The presence of a polyfunctional epoxy compound, e.g, epoxidized peanut oil, which functions as a heat or light stabilizer in given compositions is classified elsewhere, e.g., in various subclasses of Class 524.
