    • This invention is a solution process for the preparation of high molecular weight ethylene-.alpha.-olefin-diolefin copolymers comprising contacting ethylene, one or more .alpha.-olefin monomer, and optionally one or more diene monomer, with a catalyst system at a polymerization temperature at or above about 80.degree. C., ethylene, one or more .alpha.-olefin monomer, and optionally one or more diene monomer, with a catalyst system comprising an unbridged Group 4 metal compound having a bulky monocyclopentadienyl ligand, a uninegative bulky Group 15 ligand and two uninegative, activation reactive ligands and a catalyst activator compound. The process can be advantageously practiced a reaction temperature of at least 80.degree. C., most preferably above 100.degree. C., to achieve high number average molecular weight polymer having high .alpha.-olefin monomer and diene monomer contents with high diene conversion rates. The process is particularly suitable for the preparation of elastomeric ethylene-propylene or ethylene-propylene-diene monomer elastomers.
