用ＤＳＣ研究了熔融时间（ｔｍｅｌｔ）和退火结晶时间（ｔａ）以及聚苯硫醚（ＰＰＳ）对聚醚醚酮（ＰＥＥＫ）多熔融行为的影响。ＰＰＳ加入使ＰＥＥＫ熔融多峰移向高温，易于形成熔融３峰。随ｔａ延长及ＰＰＳ含量增加，低温峰移向高温，高温峰移向低温，而在中间峰温区形成单一高而尖的熔融峰。在接近ＰＥＥＫ熔点温度退火时，发现共混物中ＰＥＥＫ的熔点比纯ＰＥＥＫ的高。
The effect of melting time (tmelt) and annealing crystallization time (ta) and polyphenylene sulfide (PPS) on the poly-melt behavior of polyetheretherketone (PEEK) were investigated by DSC. PPS join PEEK melt multi-shift to high temperature, easy to form melt 3 peak. With the prolongation of leaching and the increase of PPS content, the low temperature peak shifts to high temperature, the high temperature peak shifts to low temperature, while the single high peak sharp melt peak forms in the middle peak temperature. Upon annealing near the melting temperature of PEEK, the melting point of PEEK in the blend was found to be higher than that of pure PEEK.
