【摘要】 酚酞型聚醚酮可显著改善聚苯硫醚的冲击韧性，本工作运用差示量热扫描技术（ＤＳＣ），研究了聚苯硫醚及聚苯硫醚／酚酞型聚醚酮共混物的非等温结晶动力学，定量计算了有关参量。结果表明，含１０％（质量）酚酞型聚醚酮的聚苯硫醚具有最高的结晶能力，据此探讨了酚酞型聚醚酮对聚苯硫醚结晶行为的影响。更多还原

【Abstract】 The non-isothermal crystallization kinetics of polyphenylene sulfide(PPS)and its blends with polyaryletherketone bearing phthalidylidene group(PEK_C)was investigated by differential scanning calorimetry.The experimental data were evaluated quantitatively.It is found that the blend of PPS incorporating with 10%(mass)PEK-C has the maximum crystallizability.The mechanism involved in the effect of PEK-C on PPS crystallization behaviour was proposed.更多还原
