Precise synthesis of unsaturated polyolefins by nonbridged half-titanocenes

Abstract

Copolymerization of ethylene with 7-methyl-1,6-octadiene and 4-vinyl-1-cyclohexene was explored by nonbridged-half titanocenes. Consequently, copolymer possessed olefinic double bond in the side chain without side reaction was obtained by optimization of catalyst system. Additionally, the copolymerization mechanisms were explored by comparison with ethylene/1-octene and ethylene/vinylcyclohexene.
