Copolymerization of Ethylene and α-Olefin Catalyzed by Cp_2ZrCl_2/Al(iBu)_3/B(C_6F_5)_3

Copolymerization of ethylene/α-Olefin with Cp_(2)ZrCl_(2)/Al(iBu)_(3)/B(C_(6)F_(5))_(3) catalystic system was investigated. The copolymerization activity changes with the differentα-Olefin type used and the α-Olefin feed concentration. The molecular weight distribution of copolymer prepared by Cp_(2)ZrCl_(2)/Al(iBu)_(3)/B(C_(6)F_(5))_(3) catalystic system is narrower than the copolymer prepared by Cp_(2)ZrCl_(2)/MAO catalystic system, and copolymerization is proved by()~(13)C-NMR.
