Abstract:研究了聚合温度在30~60 ℃,以正丁基锂为引发剂、环己烷为溶剂、二硫化碳为结构调节剂的异戊二烯负离子聚合的反应规律,以及二硫化碳用量和聚合条件对聚异戊二烯微观结构的影响.结果表明,随着异戊二烯/环己烷的增加,聚异戊二烯中的顺式-1,4-结构含量降低;随着引发剂浓度的增加,顺式-1,4-结构含量也降低;随着反应温度升高,顺式-1,4-结构含量先增加后降低;随着二硫化碳用量的增加,顺式-1,4-结构含量先增加后略有降低.在50 ℃、异戊二烯/环己烷(质量比)为1/9、正丁基锂/异戊二烯(摩尔比)为0.68×10-3及二硫化碳/正丁基锂(摩尔比)为0.08×10-3时可制得顺式-1,4-结构摩尔分数最高约为96%的高顺式聚异戊二烯.
