Patent ID: 7999039

Claim:
A process of making a polymer, comprising: a) contacting one or more olefinic monomers in the presence of at least a high molecular weight (HMW) catalyst and at least a low molecular weight (LMW) catalyst in a polymerization reactor system, wherein the HMW catalyst and LMW catalyst have substantially the same comonomer incorporation; and b) effectuating the polymerization of the one or more olefinic monomers in the polymerization reactor system to obtain an olefin polymer, wherein the LMW catalyst produces a polymer having an R v L , defined as R v L = [vinyl] [vinyl] + [vinylidene] + [cis] + [trans] wherein [vinyl] is the concentration of vinyl groups in the olefin polymer produced expressed in vinyls/1,000 carbon atoms; [vinylidene], [cis] and [trans] are the concentration of vinylidene, cis and trans groups in the olefin polymer expressed in the number of the respective groups per 1,000 carbon atoms, of greater than 0.12, wherein the HMW catalyst is (N-(1,1-dimethylethyl)-1,1-di-(4-n-butyl-phenyl)-1-((1,2,3,3a,7a-η)-3-(1,3-dihydro-2H-isoindol-2-yl)-1H-inden-1-yl)silanaminato-(2-)-N—) dimethyltitanium and the LMW catalyst is rac-[1,2-ethanediylbis(1-indenyl)]zirconium (1,4-diphenyl-1,3-butadiene), wherein the HMW catalyst has a reactivity ratio, r1 of about 5 or less, wherein the high molecular weight catalyst produces a polymer having an R v H defined as R v H = [vinyl] [vinyl] + [vinylidene] + [cis] + [trans] wherein [vinyl] is the concentration of vinyl groups in the olefin polymer produced expressed in vinyls/1,000 carbon atoms; [vinylidene], [cis] and [trans] are the concentration of vinylidene, cis and trans groups in the olefin polymer expressed in the number of the respective groups per 1,000 carbon atoms, and wherein a ratio of R v L /R v H ranges from 0.5 to about 2.0.
