Abstract:
1. A method of polymerizing poly(cyclic)olefin monomers comprising: combining a monomer composition comprising one or more poly(cyclic)olefin monomers, a non-olefinic chain transfer agent and an activator compound in a reaction vessel to form a mixture; and adding a polymerization catalyst containing Ni, the polymerization catalyst causing the mixture to polymerize; wherein the non-olefinic chain transfer agent includes one or more compounds selected from the group consisting of alkylalkoxysilanes, alkylgermanes, alkylalkoxygermanes, alkylstannanes, and alkylalkoxystannanes; wherein the polymerization catalyst containing Ni is selected from the group consisting of, (i) polymerization catalysts containing Ni represented by Formula (XII), (ii) polymerization catalysts containing Ni represented by Formula (XI), wherein the activator is characterized as having a functional group containing an active hydrogen with a pKa of at least about 5.
