ABSTRACT:
A catalyst and process for the polymerization of cyclic olefins, such as dicyclopentadiene, are disclosed. The catalyst includes a transition metal compound and a borohydride co-catalyst, with optional boron halide promoter. Polymerization can be carried out in a reaction injection molding process to prepare a thermoset molded article.
