本工作采用正丁基锂(简称Li)-乙二醇二甲醚(简称1G)引发体系,对丁二烯(简称B)和苯乙烯(简称S)在环己烷中的共聚合进行了研究。当1G/Li-1.O(摩尔比)、聚合温度为50℃时,测得表观竞聚率为:rB=1.99±0.16;rs=0.60±0.10。
In this work, n-butyllithium (Li) -ethylene glycol dimethyl ether (abbreviated as 1G) initiator system was used to copolymerize butadiene (abbreviated as B) and styrene (abbreviated as S) in cyclohexane the study. When 1G / Li-1.0 (molar ratio), the polymerization temperature was 50 ℃, the apparent reactivity ratio was measured as follows: rB = 1.99 ± 0.16; rs = 0.60 ± 0.10.
