Patent ID: 7781549

Claim:
A slurry process which comprises polymerizing ethylene at a temperature within the range of 40° C. to 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 low long-chain branching as indicated by a viscosity enhancement factor of less than 2.0, wherein the process forms polyethylene having weight-average molecular weight greater than 250,000, wherein the process has good hydrogen sensitivity such that introduction of 0.82 mmoles of hydrogen per mole of ethylene into the liquid phase reduces the weight-average molecular weight by at least 60%, and wherein the complex has the structure: wherein each R 1 is independently selected from the group consisting of C 1 -C 6 n-alkyl; each R 2 is independently selected from the group consisting of H and C 1 -C 10 hydrocarbyl; and each L is independently selected from the group consisting of halide, alkoxy, aryloxy, siloxy, alkylamino, and C 1 -C 30 hydrocarbyl.
