The research progress and application of cis-butadiene-isoprene copolymer rubber(CBIR) were addressed. And the development tendency of cis-butadiene-isoprene copolymerization were reviewed.

The synthesis of 2,3- DCB /MMA Copolymer and preparation of the adhesive for bonding rubber to metal with the copolymer above as the main material are introduced.

Synthetic rubber is a copolymer of butadiene (75%) and styrene (25%).
