| 摘 要： | <正> 顺丁橡胶与丁苯橡胶在性能上的差别,在于其分子主链上缺少象苯基那样的侧基。而中乙烯基聚丁二烯的分子主链上有相当数量的乙烯基侧基,它弥补丁顺丁胶的不足之处。故日益受到人们的注意。目前,已工业化的中乙烯基聚丁二烯所用的催化剂为烷基锂体系,其聚合物除了1,2-结构外,其余部分反-1,4结构占多数。我们在前文曾经报

| Abstract: | Allyl halide or benzyl chloride can greatly regulate the molecular weight of polymer during the polymerization of butadiene in hydrogenated gasoline with PeCl3-(i-C4H9)3Al-phen catalyst system. It was found that allyl chloride is the most effective regulator of molecular .weight among them. The 17] of polybutadiene can be lowered from over 1.0 M3/kg to less than 0.4 M3/kg by the addition of allyl chloride, while the polymerization keeps high yield. Polybutadiene rubber with mid-vinyl structure was obtained and it has good properties. |
