摘　　要：随着共轭二烯烃的广泛应用,对聚共轭二烯烃橡胶的性能有了更高要求。通过调整聚合途径进而获得特定的聚合物链结构,可以满足多样化的工业需求。本文综述了钕催化体系对聚共轭二烯烃链结构调控的研究,重点阐述了配位聚合中链转移聚合方法对聚共轭二烯烃的构型选择性和分子量及其分布的调控,总结了钕催化体系催化极性单体和烯烃单体共聚的研究进展。With the widespread application of conjugated dienes,there were higher requirements for the performance of poly(conjugated dienes)rubber.By adjusting polymerization pathway,specific polymer chain structures could be obtained to meet diverse industrial needs.The research progress in regulation of chain structure of conjugated dienes by neodymium based catalytic systems were reviewed with 29 references,with a focus on the regulation of configuration selectivity and molecular weight and their distribution of conjugated dienes by chain transfer polymerization methods in coordination polymerization.The copolymerization of polar monomers and olefin monomers catalyzed by neodymium based catalytic systems were summarized.
