摘要 用BCl3为修饰剂制备了改性甲基铝氧烷(BMAO) 以二氯二茂锆为主催化剂、BMAO为助催化剂,考察了影响乙烯聚合活性的各种因素及其聚合动力学行为 与常用的甲基铝氧烷(MAO)相比,BMAO用于催化体系显著提高了乙烯聚合的催化活性. Boron chloride modified methylaluminoxane(BMAO) was prepared. It was found that the activities of ethylene polymerization catalyzed by Cp_(2)ZrCl_(2)/BMAO catalytic system were higher than Cp_(2)ZrCl_(2)/MAO catalytic system.
