| 摘 要： | 分析了五种醇与WCl6在室温下交换反应产物氯含量,表明产物中W:Cl=1:4,故产物可写为WCl4(OR)2。以WCl4(OR)2-Al(i-Bu)3为催化体系,在加氢汽油溶剂中可使丁二烯聚合,得到1,2-链节含量在80%,全同立构体在60%以上的聚合物。几种醇中,以n-C10H21OH交换产物的催化活性最高。各种聚合条件的改变,对聚合物微观结构及分子量分布影响不明显。

| Abstract: | This paper discusses the exchange reaction between WCl6 and four alcohols: n-C4H9OH,n-C5H11OH, t-C7H15OH and n-C10H21OH. The results show that the products of the reaction may be represented as WCl4(OR)2, The content of 1,2-unit in polymer prepared with WCl4(OR)2 -Al(i-Bu)3 catalyst in hydrogenated gasoline is found to be about 80% and the catalyst system with R=n-C10H21O gives the highest activity. The molecular weight distribution is independent of the polymerization conditions used. |
