Abstract:采用阴离子聚合制备了线型和星型液体丁二烯-苯乙烯嵌段共聚物(LBSC)、含渐变段共聚物和无规共聚物.采用甲酸-H2O2原位法对上述LBSC进行了环氧化反应.考察了H2O2用量、环氧化反应时间和温度、相对分子质量、苯乙烯含量和序列结构等对LBSC环氧化反应的影响;研究了环氧化液体丁苯共聚物(ELBSC)偶联剂对聚丁二烯活性链末端偶联反应的影响.结果表明:控制H2O2用量可以得到环氧值可控的ELBSC,当H2O2与丁苯共聚物中聚丁二烯双键的摩尔比为0.6,反应时间在120min,温度在50℃时可达到最大环氧值;随着ELBSC用量的增加,偶联效率逐渐增大,相对臂数逐渐减小,在环氧基团与锂的摩尔比为1.0时偶联效率最大.
