Diene/olefin/polar monomer copolymerisation: unprecedented functional polymers from a rare earth catalyst

Abstract
An ansasamarocene allyl system is an efficient initiator which polymerises 1,3‐dienes, copolymerises dienes and long‐chain α‐olefins or α,ω‐dienes to give functionalisable polymers. It also polymerises caprolactone and allows the controlled diblock copolymerisation of isoprene or isoprene/α‐olefin copolymer and caprolactone.© 2002 Society of Chemical Industry
