摘要
本文研究了WCl_6-C_4H_9OH-Al(i-Bu)_2 OPhCH_3体系催化合成1,2-聚丁二烯的动力学特征,测定了单体、主催化剂和助催化剂的反应级数,建立了稳态期聚合速率方程,求得其表现活化能及Arrhenius因子,并对其反应动力学机理作了初步讨论。
The kinetics of butadiene polymerization with WCl6-C4H9OH-Al(i-Bu)2OPhCH3 as catalyst was studied. The orders of reaction for the monomer, the catalyst and the cocatalyst were determined respectively and the rate equation of the polymerization was estabilished. At the same time, the activation energy and Arrhenius factor were known. Based on the equation, the polymerization mechanism of the reaction was also put forward.
