Abstract

Rare activity of an active rare-earth-metal catalyst is observed in the alternating copolymerization of ethylene and norbornene. The reaction yields exclusively the alternating copolymer in the presence of both monomers and affords poly(ethylene-alt-norbornene)-b-polyethylene block copolymers when a relatively small quantity of norbornene is used under a constant flow of ethylene (see scheme).
