摘要： 以萘锂为引发剂,抽余油为溶剂,探讨了醋酸乙烯与活性聚丁二烯基锂之间的反应机理。研究结果表明,醋酸乙烯加至活性聚丁二烯溶液中后,主要发生了偶联反应。同时,还向高分子链中引入了羟基。

Abstract: The mechanism of the reaction between acetate and polybutadienyl-lithium was inqui-red by using naphthalenelithium as initiator in extracted naphtha solution. It was found that a coupling reaction occurs after vinyl acetate and polybutadinyl lithium have been brou-ght together in an evacuated vessel acompanyied by a simultaneous introduce of hydroxyl groups into the polymer chain。
