Patent ID: 7449529

Claim:
An article of manufacture comprising polymer produced by a process comprising: a. contacting one or more olefin monomers together in the presence of a catalyst under polymerization conditions, wherein said catalyst is produced by a process comprising: i. contacting an alkyl magnesium compound with an alcohol to form a magnesium dialkoxide compound; ii. contacting said magnesium dialkoxide compound with a first agent to form a reaction product “A”, wherein said first agent is selected from ClTi(O i Pr) 3 , ClSi(Me) 3 and combinations thereof; iii. contacting said reaction product “A” with a second agent to form reaction product “B”, wherein said second agent is TiCl 4 /Ti(OBu) 4 ; iv. contacting said reaction product “B” with a third agent to form reaction product “C”, wherein said third agent is TiCl 4 ; v. contacting said reaction product “C” with a fourth agent to form reaction product “D”, wherein said fourth agent is TiCl 4 ; and vi. contacting said reaction product “D” with a fifth agent to form said catalyst; and b. extracting said polymer, wherein said polymer is bimodal and has a molecular weight distribution of at least 10.
