| 摘 要： | 研究了负载钛催化剂引发丁二烯在0～40℃的本位沉淀聚合动力学。结果表明，体系在单体液相未消失之前转化率与时间成直线关系，即聚合速率恒定、表现为稳态聚合，丁二烯本位沉淀聚合的表现活化能为33.5kJ/mol，一定条件下的聚合速率方程为：Rp=kpBd]oTi]oAl]o。

| Abstract: | The kinetics of bulk precipitation polymerization of butadiene with supported titanium catalysts was studied at 0～40 ℃. The results show that there is a steady polymerization character in this system before the monomer liquid phase disappearing. The apparent active energy calculated was about 33.5 kJ／mol. The kinetic equation of the bulk precipitation polymerization was obtained:Rp=kp［Bd］0［Ti］0［Al］0. |
