Abstract:
1. A method for polymerizing olefinic monomers comprising contacting an olefinic monomer or monomers under polymerization conditions with a catalyst composition comprising the reaction product of: (a) a compound represented by the formula: and (b) an activating co-catalyst; where R 1 and R 2 are independently hydrogen, C 1 to C 12 linear and branched alkyl, C 3 to C 12 cycloalkyl, aryl, C 1 to C 12 alkoxy, F, Cl, SO 3 , C 1 to C 12 perfluoroalkyl, and N(CH 3 ) 2 , R A is —CH(R where R 4 is a hydrocarbyl, halosubstituted hydrocarbyl, or alkoxy group of from 1 to 12 carbon atoms, x is an integer from 1 to 12, and Y is halogen, and X is halogen, triflate, acetate, trifluoroacetate, hydride, or tetrafluoroborate.
