聚芳醚砜-聚醚氨酯嵌段共聚物的合成工艺研究

Research on Synthesis Conditions of Polyarylsulphone-Polyetherurethane Block Copolymer

通过端二异氰酸酯聚醚预聚物与齐聚醚砜二酚模型物的氢转移加成聚合反应合成了一系列聚芳醚砜－聚醚氨酯嵌段共聚物。得到了聚合反应的适宜条件：二甲基甲酰胺作溶剂，甲苯作稀释剂，使反应物质量浓度为３５％ ，以环三乙烯二胺作催化剂，反应温度１００℃。

A series of polyarylsulphone\|polyetherurethane block copolymers are synthesized through hydrogen polyaddition of diisocyanate terminated poly(oxypropylene)ether with polyethersulphone diphenol.The appropriate conditions of polyaddition are found:the best solvent is N,Ndimethylacetamide,the diluent is toluene,the best catalyst is triethylace diamine,the concentration of reactants should be 35%,and the appropriate reaction temperature is 100℃.
