摘要
酞侧基聚芳醚砜（ＰＥＳ－Ｃ）与聚苯硫醚（ＰＰＳ）具有部分相容性，虽然ＰＰＳ的强度和韧性均低于ＰＥＳ－Ｃ，但ＰＰＳ含量为２％～１０％的ＰＥＳ－Ｃ／ＰＰＳ共混物在保持ＰＥＳ－Ｃ原有强度、断裂伸长率的同时，模量略增，冲击强度有很大幅度提高，熔融指数亦有增加。
The morphology and mechanical properties of PES-C/PPS blends have been stud-ied by means of DSC,DMA,SEM and mechanical characterization. The blends are partlycompatible. It is interested that, though the strength and ductility of PPS is lower than thatof PES-C, at low content of PPS the impact strength of PES-C can be improved markedlywithout changing its tensile strength and elongation at break.The melt index of the blendsalso increases with increasing PPS content.
