摘要：
Highly selective ring opening metathesis polymerization (ROMP) of norbornene can be achieved using a new Ru(II)-vinylidene complex as catalyst precursor. The polymerization reaction proceeds in 1,2-dichloroethane at 80 degrees C in absence of co-catalysts with high turnover frequencies. The molecular weight and molecular weight distribution of the polymers obtained indicate that different species are active in the catalytic process. (C) 1999 Elsevier Science Ltd.
