摘　　要：超支化聚苯硫醚（HPPS）的分子呈不规则的三维准球形结构,分子中存在大量结构上的缺陷和残缺的支链,还包括部分线性结构单元;官能团部分位于分子表面,部分存在于分子内部;其相对分子质量分布较宽,支化度在0~1之间。介绍了HPPS的合成机理、掺杂导电性,以及其共混材料和嵌段共聚物材料的性能。The hyperbranched poly（phenylene sulfide）（HPPS） molecule has an irregular three-dimensional quasispherical structure. A large number of structure defects and incomplete branched chains exist in the molecule, and partial linear structure units are also included. The functional groups locate both in the surface and interior of molecule. HPPS has a broad relative molecular weight distribution, and its degree of branching is 0-1. The synthesis mechanism and doping conductivity of HPPS, as well as the properties of its blending materials and block copolymers are introduced.
