摘要 用Cp2ZrCl2/Al(iBu)3/B(C6F5)3催化体系催化乙烯与α-烯烃的共聚合,发现共聚合活性随着α-烯烃的种类和浓度的不同而有较大的变化.与传统的Cp2ZrCl2/甲基铝氧烷催化体系相比,聚合活性在同一数量级;凝胶渗透色谱的测定表明共聚产物分子量分布较窄,13C-NMR证实了共聚反应的发生. 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.
