| 摘 要： | 研究了络合Ⅱ型 TiCl_3经1-辛烯预聚处理后用于1-辛烯聚合的聚合动力学规律。通过改变预聚条件,得到了两种类型的动力学曲线。发现预聚过程中催化剂 TiCl_(?)颗粒逐渐破碎,而破碎程度又取决于预聚条件,解释了导致不同类型动力学曲线的原因。

Effects of Prepolymerization on Kinetics of 1-Octene Ziegler-Natta Polymerization |
| |
| Abstract: | The kinetics of 1-octene polymerization on complex Ⅱ TiCl_3-Al(Et)_3 catalysttreated by prepolymerization of 1-octene was studied.Two kinds of kinetics curvescould be obtained by changing the conditions of prepolymerization.It was dis-covered that the catalyst particles of TiCl_3 broke in the process of prepolymeriza-tion and the degree of the catalyst break depend d on the conditions of prepoly-merization.The reasons for obtaining different kinds of kinetics curves were explained. |
