Abstract
Poly(phenylene sulfide)[PPS]의 유도체인, poly(phenylene sulfide sulfone)[PPSS] 및 Poly(phenylene sulfide ether)[PPSE]를 합성한 뒤 이들의 열적 성질들을 DSC와 TGA를 사용하여 조사하였으며, PPSE의 경우는 DSC의 isothermal darta와 Avrami equation으로 부터 이들의 결정화거동도 함께 조사하였다. PPSS는 비결정성고분자로서 유리전이온도(Tg)가 215℃였다. PPSE의 경우는 PPS와 마찬가지로 결정성고분자였으며 Tg가 47℃, Tm이 195℃, cold crystallization temperature(Tcc)가 78℃이었다. 이는 PPS(Tg, 83℃ ; Tm, 279℃ ; Tcc, 124℃)와 비교할 때 훨씬 낮은 온도 이었다. 또한 PPSE의 경우가 PPS보다 열적안정성이 우수하였으며, 최대결정화도를 나타내는 온도는 낮았고 결정화속도는 더욱 큰 것으로 나타났다. Poly(phenylene sulfide)[PPS] and its derivatives ; poly(phenylene sulfide sulfone)[PPSS], poly(phenylene sulfide ether)[PPSE], were synthesized and their thermal properties were investigated by DSC and TGA. In case of PPSE, the crystallization behavior was also studied by isothermal data from DSC and Avrami equarion. PPSE and PPS show high crystallinity, while PPSS is totally amorphous. Glass transition temperature(Tg), melting temperature(Tm), and maximum crystallization temperature of PPSE have much lower than those of PPS. On the other hands, thermal stability and crystallinity of PPSE were relatively higher than those of PPS.
