摘要

The identities and yields of the low-molecular-weight products formed during ring-opening polymerization of norbornene in benzene solvent using several unicomponent metal halide catalysts (W, Mo, Re, Ru, Os and Ir) were extensively investigated. Dimers and trimers were observed in all cases but were only substantial relative to polymer yields for WCl6 and ReCl5. The rate of formation of the dimers exactly paralleled that of the ring-opened ...
