| 摘 要： | 本工作对复合载体乙丙共聚催化体系TiCl_4/MgCl_2/NaY进行了ESR观察,发现在TiCl_4/MgCl_2/NaY体系中有多种顺磁中心存在,其中起码有一种是活性中心。并且发现复合载体有较强的负载能力。复合载体催化体系对不同结构的烯烃共聚有选择性,对聚合物的结构有调控作用。

| Abstract: | In this paper, complex carrier catalytic system TiCl4/MgCl2/NaY for copolymerization of ethy-lene and propylene was studied using ESR technique. For the first time,it was found in TiCl4/MgCl2/ NaY system there were multi-paramagnetic centers and one active center at least. It was identified that capability supported by complex carrier was stronger than that of the single carrier. The relationship between the composition of complex carrier catalysts and the structure of copolyrner were also investigated. |
