摘　　要：探究了硅桥联双脒基钛络合物催化乙烯聚合反应的压力、温度以及助催化剂与钛络合物摩尔比等条件对催化体系活性影响。实验结果表明,该体系催化活性可达到9.08×104 g·mol-1·h-1;与类似均相催化体系比较,有合成方法简单、催化活性较高的特点。The catalytic activity of the silyl-bridged bis（amidinate） titanium complex under different poly- merizations including the ethylene pressure, temperature and the A1/Ti molar ratio were examined. Poly- ethylenes（PE） were obtained and a series of experimental data shown the highest catalytic activity can reach up to 9.08 X 104 g .mo1-1.h-1. The catalytic activity were analyzed by compared with the homoge- neous catalytic systems.
