| 摘 要： | 为进一步开发新犁的可控制形态催化剂，对球形MgCl2载体催化剂的乙烯-己烯共聚合行为进行了研究。随着1-己烯加入量的增加，催化剂活性增大，共聚物的熔点和密度均降低．聚合物形态具有较好的复现性。同时发现，催化剂活性和共聚物性质随给电子体种类和加入方式的不同，发生明显的变化。

| Abstract: | In order to develop new morphology-controlled catalyst, the performance of MgCl2 supported catalyst in ethylene-hexene copolymerization was studied. The activity of catalyst went up and the melting point and density of copolymer decreased with increasing of hexene amount. The morphology of copolymers had favorable repetition. Meanwhile the activity of catalyst and properties of copolymers changed apparently as the type and added method of electron donor. |
