Patent ID: 8114946

Claim:
An olefin polymerization process, which comprises: contacting a catalyst composition with an olefin monomer and at least one olefin comonomer under polymerization conditions to produce an olefin polymer, wherein the catalyst composition comprises a contact product of at least one metallocene compound and at least one activator, wherein the at least one metallocene compound has the formula: wherein: M 1 is Ti, Zr, or Hf; X is independently F; Cl; Br; I; methyl; phenyl; H; BH 4 ; OBR A 2 or SO 3 R A , wherein R A is an alkyl or aryl group having up to 12 carbon atoms; or a hydrocarbyloxide group, a hydrocarbylamino group, or a hydrocarbylsilyl group, any of which can have up to 20 carbon atoms; E is C or Si; R 1 and R 2 are independently H or an alkyl or aryl group having up to 12 carbon atoms, wherein at least one of R 1 and R 2 is an aryl group; R 3A and R 3B are independently H or a hydrocarbyl or hydrocarbylsilyl group having up to 20 carbon atoms; R 4 is an alkyl or alkenyl group having up to 10 carbon atoms; and R 5A and R 5B are independently H or a hydrocarbyl group having up to 12 carbon atoms; and wherein the polymerization process is conducted in the presence of hydrogen; the olefin polymer has a reverse comonomer distribution; and the olefin polymer has a ratio of Mw/Mn from about 3 to about 6.
