热塑性聚硅氧烷-聚脲嵌段共聚物的研究进展

摘要

综述了近年来通过聚硅氧烷与聚脲的嵌段共聚合成热塑性弹性体的相关研究进展，介绍了二元和三元嵌段共聚弹性体的合成方法，讨论了影响弹性体性能的主要因素———氢键、软链段、硬链段、扩链剂以及溶剂，总结了弹性体新合成方法和在性能提高上取得的突破，并对该领域的研究做出了展望。%The research progress on the segmented thermoplastic copolymers synthesized by polysiloxane-polyurea in recent years was reviewed. The paper introduced different synthesis methods of binary and ternary segmented copolymers and discussed the factors which influenced the elastomers on hydrogen bonding, soft and hard segment, chain extender and solvents. Then it summarized some new synthesis methods and breakthrough on elastomer’ s performance as well as the prospect in the fields.
