| 摘 要： | 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。

| Abstract: | 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. |
