dc.description.abstract Poly(phenylene sulfide sulfone)[PPSS]를 시간과 온도를 변화시키면서 열처리를 하였을 때 이들의 유리전이 온도(Tg)를 DSC로서 조사하였다. 그 결과 PPSS의 Tg는 열처리온도가 230℃까지는 열처리 시간이 길어질수록 증가하다가 평형에 도달하였다. 열처리 온도가 245℃ 이상에서는 열처리 시간이 길어질수록 Tg가 증가하다가 어느 정도 시간이 되면 감소한 뒤 다시 증가하는 것으로 나타났다. 이 현상을 경화가 진행됨에 따른 chain extension반응과 oxidative crosslinking 및 thermal crosslinking으로 설명하였다.

Glass transition temperatures(Tg) of poly(phenylene sulfide sulfone) [PPSS], which were heat treated at various temperature and time, were studied by DSC. Up to 230℃, Tg of heat treated PPSS were increased with increasing the heat treated time. When the sample was heated at 260℃ for 30 minute and 280℃ for 10 minute, however, Tg of those samples were decreased. These phenomena can be explained by the factors of chain extension reaction, oxidative crosslinking, and thermal crosslinking.
