摘要
研究了以乙二醇二乙氨基乙基丁基醚(GABE)为调节剂,正丁基锂为引发剂的丁二烯负离子聚合的聚合动力学及聚合物的微观结构。结果表明,随着GABE用量的增加,丁二烯的聚合速率增加,聚丁二烯中 1, 2-结构质量分数增加,聚合温度升高,聚合速率增加,但聚丁二烯中 1, 2-结构质量分数有所降低。
The polymerization kinetics and microstructure of polymer about anionic polymerization of butadiene, n-BuLi as initiator, diethylene glycol 2-(N,N-diethylamino)ethyl butyl ether (GABE) as modifier, were studied. The results showed that with the increase of GABE/n-BuLi, the polymerization of butadiene became quickly and the 1,2-unit in polybutadiene increased. With the increase of polymerization temperture from 40 ℃ to 60 ℃, the polymerization also became quickly. However, the 1,2-unit in polybutadiene decreased.
