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。
In this paper, the kinetic characterization of 1,2-polybutadiene catalyzed by WCl_6-C_4H_9OH-Al (i-Bu) _2 OPhCH_3 system has been studied. The reaction order of monomer, procatalyst and cocatalyst has been determined. Period polymerization rate equation, to obtain the expression of activation energy and Arrhenius factor, and its reaction kinetic mechanism was initially discussed.
