Abstract:
1. A process for polymerization of ethylene and one or more C 3-30 α-olefins or diolefins under continuous, solution polymerization conditions to prepare a high molecular weight interpolymer having narrow molecular weight distribution and improved processability, 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 T R wherein a chain transfer agent is present in an amount sufficient to decrease the Mw of the resulting interpolymers at least 10 percent compared to the molecular weight of the resulting polymer prepared in the absence of a chain transfer agent, the polymerization is conducted at a temperature from 120° C. to 250° C., the ethylene conversion is at least 85 mol percent and the resultant polymer has a density between 0.855 and 0.950 g/cm
