摘　　要：以液体聚丁二烯(LPB)为代表的二烯类不饱和聚合物因其成熟稳定的生产技术、相对低廉的成本和聚合物分子链中大量存在的活性双键而成为化学改性的理想聚合物。各种活性官能团或特殊性能链段的引入赋予了改性LPB全新的物理化学性能,极大地拓展了LPB的应用范围。本文综述了LPB官能化改性技术的研究进展,重点介绍了端基官能化、侧链官能化和接枝改性及嵌段共聚改性,并对其发展前景进行了展望。Diene unsaturated polymers,represented by liquid polybutadiene(LPB),had become ideal polymers for chemical modification due to their mature and stable production technology,relatively low cost and abundant active double bonds in polymer molecular chains.The introduction of various active functional groups or special performance segments endowed modified LPB with new physical and chemical properties,which greatly expanded the application range of LPB.In this paper,the research progress of LPB functional modification technology was reviewed with 59 references.The end-group functionalization,side chain functionalization and grafting modification,and block copolymerization modification were emphatically introduced,and the development prospects were prospected.
