以rac-(dimethylsilyl)bis(4，5，6，7-tetrahydro-1-indenyl)zirconium二氯化铝为催化剂，甲基铝氧烷为助催化剂，在0~10 0℃温度范围内对1-己烯进行聚合，研究了聚合速度、聚合物相对分子质量和聚合物微观结构(立体专一性和区域专一性)随温度以及单体、催化剂和助催化剂浓度的变化规律。
1-Hexene was polymerized by rac-(dimethylsilyl)bis(4,5,6,7-tetrahydro-1-indenyl)zirconium dichloride catalyst and methylaluminoxane cocatalyst over the temperature range 0-100 °C. The polymerization rate, polymer molecular weight, and polymer microstructure (stereospecificity and regiospecificity) were studied as a function of the temperature and the concentrations of monomer, catalyst, and cocatalyst.
