Epoxidation of olefin/diene copolymers using hydrogen peroxide
A process for preparing an epoxidized α-olefin/diene copolymer including the steps of contacting in a reaction medium a) copolymers of an α-olefin and a diene, which copolymers contain at least one double bond in each diene-derived co-monomer, with b) a hydrogen peroxide epoxidizing agent, in the presence of a perfluorinated alcohol reaction solvent, and in the absence of any metal-containing epoxidation catalyst, under reaction conditions which promote formation of oxirane rings at the sites of the diene-derived co-monomer double bonds in the copolymeric precursor material.
