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