DEFINITION

Classification: 525/523

Solid polymer contains more than one 1,2-epoxy group or is derived from reactant containing at least one 1,2-epoxy group:

(under subclass 50) Subject matter involves processes of mixing a solid polymer containing more than one 1,2-epoxy group per mole or solid polymer derived from a reactant

containing at least one 1,2-epoxy group with additional solid polymer, with specified polymer-forming ingredients, with chemical treating agent, or with ethylenic agent; or products resulting from the above mixing processes.
