IMPROVED CHEMICAL CURING OF EPOXIDIZED DIENE POLYMERS USING AROMATIC ANHYDRIDE CURING AGENTS

A process for curing epoxidized diene polymers for use in adhesives, sealants, and coatings which comprises contacting the polymer with an aromatic anhydride curing agent at an epoxy/anhydride molar ratio from 0.5/1 to 2.0/1.0, optionally, and from 0.1 to 10 phr of an accelerator at a temperature of...
