本文探讨了烯丙基溴对钼体系催化丁二烯聚合的影响。烯丙基溴降低了聚丁二烯的分子量而提高了1,2-链节和间同构型的含量。由于分子构造发生了变化,提高了聚丁二烯玻璃化转变温度和呈现出一定程度的结晶。加烯丙基溴体系的聚丁二烯的屈服强度比不加溴的大,两者对[η]作图,出现二条平行的直线。分子量对生胶挤出破裂的影响比分子量分布的大。硫化胶的力学机械性能比较好。 The effect of allyl bromide on butadiene polymerization catalyzed by molybdenum was investigated. Allyl bromide reduces the molecular weight of polybutadiene and increases the content of 1,2-mer and syndiotactic. Due to changes in molecular structure, polybutadiene glass transition temperature increased and showed a certain degree of crystallization. Polybutadiene plus allyl bromide yield strength than without bromine, the two [η] mapping, there are two parallel lines. The impact of molecular weight on the extrusion of plastic extrusion than the molecular weight distribution. Vulcanizate mechanical mechanical properties are better.
