This model has take into consideration the exchanges reaction between different alkylaluminiums and ED with internal donor(ID)on the surface of catalyst. It was suggested that the propylene polymerization system actually is a complicated ’multiple active center system’.
该模型从烷基铝、外给电子体与催化剂表面的内给电子体发生交换反应的观点出发,得出PP聚合体系实际是复杂的“多活性中心”体系的结论,定性地阐述了不同反应活性的助催化剂及外给电子体的对产物立构规整性的调控原理。
