ABSTRACT:
Copolymers produced by polymerization of a mixture comprising a 1,3-cyclodiene, an acyclic conjugated diene, and, optionally, a vinyl aromatic compound are epoxidized to form epoxidized copolymers exhibiting improved green tensile strength, moduli, and oil resistance properties in comparison with the unepoxidized parent copolymers.
