摘　　要：本工作以ＤＳＣ法研究了溶液共混法和机械共混法制备的聚醚砜（ＰＥＳ）和聚醚醚酮（ＰＥＥＫ）共混物（以下简称ＳＳＫ和ＭＳＫ）的相容性和热性能．实验表明ＳＳＫ为部分相容体系，相容性随ＰＥＳ含量增加而增大，热处理可以进一步提高体系的相容性；ＭＳＫ经热处理后具有一定的相容性．ＴＬ，Ｔｍ，ΔＨＬ，ΔＨｍ，Ｘｃｒ与热处理温度有关．The compatibility and crystalline property of PES-PEEK blends from mechanical way(MSK )and solution way (SSK ) was studied. The results indicated that the compatibitity of SSK blends wus much better that of MSK. The compatibility increas with the increasing of PES contents and tEe crystalline property of PEEK in blends decreases. Thermol treatment could increase the compatibility also. Tin,Te,ΔHm, ΔHe and Xcr were retated to treating temperature.
