重点介绍了工业上1，3-丁二烯“高顺”聚合使用均相催化剂的优点，并考察了预制的均相催化剂对1，3-丁二烯“高顺”聚合的催化性能。考察了改变(A)催化剂组分的加入顺序、(B)羧酸盐组分和(C)卤素组分对催化剂均匀度、活性和聚合物性能的影响。
The benefits of using a homogeneous neodymium-based catalyst for the industrial ''high cis'' polymerisation of 1,3-butadiene are underlined.Preformed homogeneous catalysts for the ''high cis'' polymerisation of 1,3-butadiene based on Nd(carboxylate)3/diisobutylaluminium hydride/(t)butyl chloride have been examined. The effects of changing (a) the order of catalyst component addition, (b) the carboxylate component and (c) the halogen component, on catalyst homogeneity, activity and polymer characteristics have been examined.
