摘要：采用桥联茂金属催化体系rac-Et(1-Ind)2Zr Cl2/Al(iBu)3/[Me2NHPh]+[B(C6F5)4]-催化1-癸烯聚合,考察了茂金属浓度、Al/Zr摩尔比、B/Zr摩尔比、温度、反应时间对反应转化率、黏度和摩尔质量的影响。当反应条件为1-癸烯20m L、甲苯20m L、Zr/烯摩尔比8×10-5、Al/Zr摩尔比80、B/Zr摩尔比1.5、温度80℃、反应时间1h时,转化率达到96.2%。采用13C NMR和1H NMR表征了产物的结构,优化条件下所得的聚合产物具有高黏度指数(259)和低分子量分布(2.088),可作为理想的润滑油基础油的原料。
Polymerization of 1-decene catalyzed by bridged metallocene catalyst system, rac-Et（1-Ind）2ZrCl2/Al（iBu）3/[Me2NHPh]＋[B（C6F5）4]-,was studied. The effects of the concentration of metallocene catalyst,Al/Zr mole ratio,B/Zr mole ratio,temperature,conversion time,viscosity and molar mass were investigated. The reaction condition was chosen as follows：1-decene 20mL,toluene 20mL,Zr/1-decene mole ratio 8×10？5,Al/Zr mole ratio 80,B/Zr mole ratio 1.5,reaction temperature 80℃,and reaction time 1h. The conversion was 96.2%. The product structure was characterized by 13C NMR and1H NMR. The polymer obtained under optimized condition has a high viscosity index （259） and a narrow molecular weight distribution （2.088）,which is a desired component for lubricating based oil.
