研究了负载钛催化剂引发丁二烯在0~40 ℃的本体沉淀聚合动力学。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。丁二烯本体沉淀聚合的表观活化能为33.5 kJ/mol。一定条件下的聚合速率方程为:Rp=kp[Bd]0[Ti]0[Al]0。
研究瞭負載鈦催化劑引髮丁二烯在0~40 ℃的本體沉澱聚閤動力學。結果錶明,體繫在單體液相未消失之前轉化率與時間成直線關繫,即聚閤速率恆定,錶現為穩態聚閤。丁二烯本體沉澱聚閤的錶觀活化能為33.5 kJ/mol。一定條件下的聚閤速率方程為:Rp=kp[Bd]0[Ti]0[Al]0。

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.
