新型给电子体对负载型丙烯聚合催化剂性能的影响研究

Study on the Effect of the Supporting Polypropane Catalyst of Novel Internal Donors

以实验室自制新型β-二酮类化合物制备了四种含有不同内给电子体(1,1,1-三氟-5,5-(二甲基)-2,4-己二酮、3-乙基-2,5-戊二酮、1,1,1-三氟-4-苯基-2,4-丁二酮、1,3-二苯基丙二酮)的MgCl2负载型丙烯聚合齐格勒-纳塔(Z-N)催化剂。研究了给电子体结构与聚合性能之间的关系。内给电子体的结构对聚合物立构规整度有较大的影响。

Four kinds of β-diketones are synthesized as Novel internal donors and the specific MgCl2 supporting Ziegler-Natta catalysts ars prepared,the relationship between the structure and properties is investigated.
