A method of polymerizing a first, and a second class of monomers to form product polymer. The first class of monomers polymerize via a radical pathway in the presence of light, and the second class of monomers polymerize via an insertion pathway in the absence of light.

A process to produce a branched ethylene--olefin diene elastomer comprising combining a catalyst precursor and an activator with a feed comprising ethylene, C3 to C12 -olefins, and a dual-polymerizable diene to obtain a branched ethylene--olefin diene elastomer; where the catalyst precursor is selected from pyridyldiamide and quinolinyldiamido transition metal complexes. The branched ethylene--olefin diene elastomer may comprise within a range from 40 to 80 wt % of ethylene-derived units by weight of the branched ethylene--olefin diene elastomer, and 0.1 to 2 wt % of singly-polymerizable diene derived units, 0.1 to 2 wt % of singly-polymerizable diene derived units, and the remainder comprising C3 to C12 -olefin derived units, wherein the branched ethylene--olefin diene elastomer has a weight average molecular weight (M.sub.w) within a range from 100 kg/mole to 300 kg/mole, an average branching index (g.sub.avg) of 0.9 or more, and a branching index at very high M.sub.w (g.sub.1000) of less than 0.9.
