POLYMERIZATION OF CYCLIC OLEFINS (DICYCLOPENTADIENE) AND A TUNGSTEN CONTAINING CATALYST USED FOR THIS POLYMERIZATION

摘要

A catalyst and process for the polymerization of cyclic olefins, such as dicyclopentadiene, are disclosed. The catalyst includes a transition metal compound, a co-catalyst and a boron halide promoter. Polymerization can be carried out in a reaction injection moulding process to prepare a thermoset moulded article having high Tg and superior flexural strength.
