以正丁基锂为引发剂,四氢呋喃为极性添加剂,环己烷为溶剂,研究了α-甲基苯乙烯与丁二烯的共聚反应动力学规律,求得了两种单体通过不同聚合活性种增长反应及解聚反应的速度常数,提出了多活性种存在下伴有解聚的共聚反应机理。
Using n-butyllithium as initiator, tetrahydrofuran as polar additive and cyclohexane as solvent, the kinetics of copolymerization of α-methylstyrene and butadiene was studied. The kinetics of copolymerization of two monomers with different polymerization activities Species growth reaction and depolymerization reaction rate constant, proposed the presence of multi-active species with depolymerization copolymerization reaction mechanism.
