结晶/结晶共混体系聚苯硫酸/聚醚醚酮中聚醚醚酮组分的结晶熔融行为──熔融温度的影响 总被引:2,自引:0,他引:2
igh performance crystal/crystal blends of poly (phenylene sulfide) and poly (ether ether ketone) (PPS/PEEK) have ho prepared by dry mixing and melhng at different temperatures. The crystallization and melting behavior of PEEK component in quenched blends have ho investigated by differential scanningcalorimetry (DSC). As melt temperature (Tmelt) increases, the crystalline andmelting behavior of PPS and PEEK is different due to the difference of thermalproperty of PPS and PEEK. The temperature of melhng (Tm) and crystallization (Tc) and crystallinity (Xc) of PEEK component in blends increase as the content of PPS increases up to 50%. However. this action of PPS is suppresed with increasing of Tmelt. 相似文献
