ABSTRACT:
A catalyst and process for the polymerization of cyclic olefins, such as dicyclopentadiene, in the presence of an elastomer polymer, are disclosed. The catalyst includes a transition metal compound, a co-catalyst and a boron halide promoter. Polymerization can be carried out at fast reaction times in a reaction injection molding process to prepare a thermoset molded article having high Tg and superior toughness.
