摘　　要：利用差示扫描量热（ＤＳＣ）、热失重（ＴＧ）和微分热失重（ＤＴＧ）研究了ＰＰＳ／ＰＡ－６６共混物的热行为和降解过程。实验结果表明，共混物具有双熔融行为。The thermal behavior and thermal degradation of PPS/PA 66 blends has been studied by means of differention scanning calorimetry (DSC), thermogravimetry (TG) and derivative thermogravimetry (DTG). It is found that blends have double melting peaks. The results showed that the degradation of the blends divided into two steps below 700 ℃ under nitrogen and atmosphere, and the onseting temperature of degradation T o and the peak temperature of degradation T p decreased with the increase of PA 66 content.
