| 摘 要： | 聚对苯硫醚poly(pphenylenesulfide),简称pPPS]的分子链是由对苯撑基和硫原子交替连接构成而使制品抗冲击能力差1](有些研究者用共聚或共混的方法在pPPS中引入间位结构来达到减少其结晶度,增强韧性的目的)。余自力等2]用硫磺溶液法合成了mPPS、pPPS及其共聚物,认为在pP...

| Abstract: | Poly(p phenylene sulfide)(p PPS) and poly (m phenylene sulfide)(m PPS) were synthesized from sodium sulfide (Na 2S), p dichlorobenzene(p DCB) and m dichlorobenzene (m DCB) in hexamethylphosphoric triamide (HMPA).Both m PPS and p PPS were characterized by elemental analysis,infrared spectroscopy,X ray diffraction and thermal analysis.The results showed that m PPS and p PPS were crystalline polymers with different crystalline structures.Tg,Tm and thermal stability of m PPS were lower than those of p PPS. |
