摘要
通过一系列聚合试验，对丁二烯在庚烷溶剂和镍基催化剂系统内的聚合行为进行了研究。认为：（１）该聚合的特点是快引发、慢增长、逐步加成、无终止；（２）诱导期外，聚合速度与单体浓度为一级关系；（３）增长链端的浓度不变。
According to a series of polymerization tests, the polymerization behaviours of butadiene in heptane solvent and nickel based catalyst system were studied with some results obtained:(1)The characteristics of the polymerization were quickly initating, slowly growing, progressively adding,nonstopping.(2)The relationship between the polymer velocity and monomer concentration was one dimension during the reaction except for the induction period.(3)The concentration of the end of the growing chain had no change.
