| 摘 要： | 采用TiCl4/MgCl2-Al(i-Bu)3催化体系在10 L聚合釜中研究了本体法1-丁烯的聚合动力学.结果表明,在反应温度为20 ℃的条件下,聚合的速率方程为Rp=157[Ti]1.1[Bt]PH20.4;在10～30 ℃时的聚合活化能为46 kJ/mol.提高催化剂浓度、聚合温度和氢气压力均能明显提高单体转化率,加快聚合速率.

| Abstract: | The kinetics of bulk polymerization of 1-butylene with TiCl4/MgCl2-Al(i-Bu)3 as catalyst in a 10 L polymerizer was studied. The results showed that the polymerization rate equation was Rp=157[Ti]1.1[Bt]PH20.4 at 20 ℃, the polymerization activation energy was 46 kJ/mol at 10-30 ℃. The monomer conversion and reaction rate increased with the increase of monomer concentration, polymerization temperature and hydrogen pressure. |
