Abstract
In this study, thermal degradation kinetics of poly(phenylene sulfide ketone)[PPSK] was investigated with thermo-gravimetric analyzer(TGA). Their thermal degradation behaviors of PPSK were investigated by dynamic thermo-gravimetry, over the temperature range 200-700 ℃ and at various heating rates of 0.5, 1, 5, 10, 50, and 100 ℃/min, respectively. Maximum degradation temperatures were in the range of 448 ℃ and 631 ℃. To determine activation energy of thermal decomposition, Kissinger method, Ozawa method, and Friedman method were used and respective activation energies were 203, 234, and 232 kJ/mol. It is advantageous to use Ozawa method in determining thermal decomposition parameter of PPSK. These parameters indicate that this material has good thermal stability.

본 연구에서는 thermo-gravimetric analyzer (TGA)를 이용하여 폴리페닐렌설파이드케톤(PPSK)의 열분해 반응을 조사하였다. 적요된 온도범위는 200-700 ℃이며 승온속도는 각각 0.5, 1, 5, 10, 50, 100 ℃/min으로 측정하였다. 최대 분해온도는 448 ℃에서 631 ℃의 범위를 보였으며 열분해 활성화 에너지를 구하기 위해 Kissinger method, Ozawa method, Friedman method를 각각 적용하였다. 분해 활성화 에너지는 203, 234, 232 kJ/mol로 측정되었고 Ozawa method가 가장 유리한 것으로 나타났으며, 구해진 열분해 파라미터를 이용하여, PP나의 내열성을 평가한 결과 비교적 우수하다고 판단되었다.
