在Nd(OCt)3*-HAl(i-Bu)2-CH2=CHCH2Cl均相催化体系下的丁二烯聚合动力学
摘要:
本文研究了丁二烯在2-乙基己酸钕-氢化二异丁基铝-烯丙基氯均相催化体系下的聚合动力学。实验结果表明,聚合速率对单体浓度和主催化剂浓度均为一级关系,对氢化二异丁基铝浓度呈1/3级关系。测得了丁二烯在本体系中聚合的表观与增长活化能以及活性中心数目。

THE KINETICS OF POLYMERIZATION OF BUTADIENE WITH Nd(OCt)3-HAI(i-Bu)2-CH2=CHCH2CI SYSTEM
Abstract:
The kinetics of butadiene polymerization with a soluble rare earth catalyst(Nd(OCt)3-HAl(i-Bu)2-CH2=CHCH2Cl) has been studied. The experimental results showed that the rate of polymerization is first order in both the concentrations of monomer and neodymium compound, but is 1/3 order in the concentration of diisobutyl aluminum hydride. The number of active center and the apparent activation energy and the propagation activation energy of butadiene polymerization were determined.
