摘　　要：采用TiCl4/MgCl2-Al(i-Bu)3催化体系在10L聚合釜中用溶液法研究了丁烯-1聚合反应过程。结果表明,在反应温度为20℃条件下,聚合的速率方程为-d[Bt]/dt=41[Ti][Bt][PH2]0.4;在10～30℃,聚合的表观活化能为16kJ/mol;提高催化剂浓度、聚合温度、氢气压力能明显提高单体转化率、加快反应速率。The reaction process of coordination polymerization of butene-1 in the presence of supported titanium catalyst in 10 L polymerizer was studied. The result showed that the rate equation was Rp=41 [Ti] [Bt] [PH2 ]0. 4 at 20 ℃, the apparent activation energy was 16 kJ/mol at the range of 10-30℃. With increasing of monomer concentration,polymerization temperature and hydrogen pressure, the monomer conversion rate and reaction rate increased.
