【Abstract】 In this paper,the basic properties of PPS are analysized and dertermined,and the relation of rheologic performance ,crystallization and thermolysis to molecular microstructure are pointed out. Rheologic analysis shows that the molecular weight is an importtant factor which can effect viscosity and processing t As the thermal history is different.it has been found that there would be some changes in the crystallinity and crystal morphology t The results of thermolytic dynamics show that PPS is the suitable material to resist the high temperature.更多还原
