Patent ID: 8299189

Claim:
A process for polymerization of ethylene, one or more C 3-30 α-olefins and one or more conjugated or nonconjugated dienes under continuous, solution polymerization conditions to prepare an interpolymer, said process comprising conducting the polymerization in the presence of a catalyst composition comprising a zirconium complex of a polyvalent aryloxyether corresponding to the formula: where: R 20 independently each occurrence is a divalent aromatic or inertly substituted aromatic group containing from 5 to 20 atoms not counting hydrogen; T 3 is a divalent hydrocarbon or silane group having from 1 to 20 atoms not counting hydrogen, or an inertly substituted derivative thereof; R D independently each occurrence is a monovalent ligand group of from 1 to 20 atoms, not counting hydrogen, or two R D groups together are a divalent ligand group of from 1 to 40 atoms, not counting hydrogen; and an activating cocatalyst at a temperature of from 80 to 250° C. and a pressure of from 100 kPa to 300 MPa.
