本文研究了BuLi-THF引发α-甲基苯乙烯与丁二烯在环己烷中阴离子共聚的共聚组成与聚合活性种的关系,建立了多活性种存在下伴有解聚的共聚组成方程,求得了不同[THF]下的单体表观竞聚率γ_1和γ_2值,并估算了它们的误差。
In this paper, the relationship between the copolymerization of α-methylstyrene and butadiene in α-methylstyrene and butadiene by anionic copolymerization in the presence of cyclohexene was studied. The copolymerization composition equation with the presence of multi-active species was established. The apparent monomer reactivity ratios γ_1 and γ_2 under different [THF] were calculated and their errors were estimated.
