以邻甲基苯酚钾(o-ROK)为助引发剂,正丁基锂(n-BuLi)为引发剂,2G为极性添加剂,二甲苯为溶剂兼链转移剂的丁二烯负离子调节聚合,考察了o-ROK在不同溶剂和不同温度下的溶解性,研究了o-ROK对丁二烯调节聚合能力和聚合物微观结构的影响规律。
In this study, butadiene negative ion-mediated polymerization with o-ROK as initiator, n-BuLi as initiator, 2G as polar additive and xylene as solvent and chain transfer agent The solubility of o-ROK in different solvents and different temperatures was investigated. The influence of o-ROK on the polymerization of butadiene and the microstructure of the polymer were studied.
