    摘要: A mixture of at least one thermal carbene-free ruthenium catalyst A and at least one thermal ruthenium carbene catalyst B, both of which initiate the ring-opening metathesis polymerization on their own, said catalysts being present in a weight ratio of A to B from 10:1 to 1:10. By adding this mixture even in small amounts, the ring-opening metathesis polymerization of strained cycloolefins can be effectively catalyzed.
