Patent ID: 7655740

Claim:
A slurry process which comprises polymerizing ethylene at a temperature within the range of about 40° C. to about 90° C. in the presence of a C 3 -C 10 α-olefin and a catalyst comprising an activator and a supported complex to produce polyethylene with good incorporation of the α-olefin and moderate long-chain branching as indicated by a viscosity enhancement factor between 2.0 and 4.0; wherein the process provides polyethylene having weight-average molecular weight greater than 250,000; wherein the catalyst has an activity ratio as defined herein greater than 2; and wherein the complex has a structure selected from the group consisting of: wherein R 1 is selected from the group consisting of methyl, benzyl, and p-chlorophenyl; R 2 is selected from the group consisting of methyl and hydrogen; each R 3 is methyl or both taken together are tetramethylene and each L is independently selected from the group consisting of halide, alkoxy, aryloxy, siloxy, alkylamino, and C 1 -C 30 hydrocarbyl.
