一种复合载体丙烯聚合催化剂的研究

The Research of a Sort of Propene Polymerization Catalyst Made by Composite Carrier

采用SiO2 MgCl2 复合载体制备了一种丙烯聚合催化剂 ,考察了SiO2 活化条件、SiO2 和MgCl2 质量比和催化剂的不同制备工艺对催化剂性能的影响 ,通过对催化剂的氢调和聚合时间的试验 ,发现该催化剂用于催化丙烯聚合时 ,无需加入外给电子化合物就可以使树脂达到较高的等规指数。

A catalyst was synthesized for propene polymerization using SiO\-2_MgCl\-2 comp osite as carrier. The effect of activation condition of SiO\-2, SiO\-2/MgCl\-2 m ass ratio and different manufacture process of this catalyst was tested. It was found that the isotactic index of resin could be achieved without addition of ex _donor in propene polymerization using this catalyst through a test of hydrogen adjusting and polymerization time.
