摘要： 本文研究了VO[OCH2C(CH3)3]2Cl-Ali-Bu3催化丁二烯、丙烯交替共聚合的动力学特征,测定了单体和催化剂的反应级数,建立了聚合速度方程,并求得了-80℃—20℃温度范围内的一级速率常数K和总活化能ET.

Abstract: A kinetic character of alternating copolymerization of butadiene and propylene based on VO[OCH2C(CH3)3]2 Cl-Al (i-Bu)3 catalyst was studied. The first order dependence on monomer and catalyst concentration was determined. It was suggested that the rate equation of copolymerization is: -d[M]/dt=ka[Cat][M]] The first order rate constant in the temperature range - 20℃——80℃ and the total activation energy were also obtained.
