Abstract

The copolymerization of ethylene and 1,7-octadiene (OD) was investigated with a constrained-geometry catalyst. The 13C NMR spectrum of the copolymer indicated cyclization insertion of the OD unit in the penultimate position after a single ethylene insertion step. This unique insertion mode of OD forms a 1,5-disubstituted cyclononane unit in the main chain of polyethylene.
