本文介绍了聚砜类共聚物的合成方法和表征手段。报道了这类材料的结构和性能。指出了由硬的无定型热塑性链段和结晶链段共聚得到的新材料的优异功能,结晶链段的存在提高了材料的耐溶剂性能和耐应力开裂性。嵌段共聚物(AB或A-B-A)可作为不相容聚合物之间或溶剂之间的相容剂。
This article describes the polysulfone copolymer synthesis methods and characterization tools. Reported the structure and properties of such materials. The excellent function of the new material obtained by the copolymerization of a hard amorphous thermoplastic segment and a crystalline segment is pointed out. The presence of the crystalline segment increases the solvent resistance and stress cracking resistance of the material. Block copolymers (AB or A-B-A) can act as compatibilizers between incompatible polymers or between solvents.
