摘　　要：简单介绍了液体聚硫橡胶的发展与性能 ,合成了以液体聚硫橡胶为软段 ,2 ,5 二氨基 3,6 二甲硫基甲苯 (E30 0 )扩链的聚硫聚脲和紫外光固化的聚硫聚脲两种聚硫聚合物 ,并介绍了用侧链含氨基的聚二甲基硅氧烷对这两种聚硫聚脲聚合物进行表面改性 ,例举了聚硫聚脲改性聚丁二烯聚脲。The development of liquid polysulfide is introduced. The synthesis, structural and mechanical properties of two polysulfide-containing polymers are described, one is polysulfide thio-polyurea, the other is UV-cured liquid polysulfide thio-urethane acrylate. Also the research work of two polysulfide-containing polymers modification with AEAPS is carried out. The application work is concluded in the last, such as epoxy toughened by polysulfide thio-polyurea, HTPB-based polyurea modified with polysulfide and so on.
