摘要

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。

Abstract

The preparation and characterization of the block copolymers of polysulfone were described in this paper. It was clearly of interest to investigate this area to establish structure-property relationships and the potential usefulness of such materials. It was reasoned that block copolymers prepared from such rigid amorphous engineering thermoplastics with a second crystalline segment would lead to vastly improved material performance. Such a system possessing an A-B-A (or A-B) structure in which the B represent a Polysulfone segment(PSF) and A represent crystalline segment e. g. PBT

HQ-PSF etc. The presence of the crystalline segment should result in an overall enhanced solvent and stress crack resistance. The results show

that A-B-A(or A-B)block copolymers can be a compatible agent for polymer-polymer system and solvent-solvent system.
