摘要: Abstract The thermal degradation of poly(phenylene sulfide sulfone) PPSS was studied by thermogravimetric analysis to determine the reaction mechanism. Several tests were carried out at different heating rates. influence rate in dynamic measurements (5–40 °C/min) on kinetic parameters, such as activation energies, also studied. energy solid-state process determined be 214 kJ/mol using Kissinger's method, which does not require knowledge value obtained Flynn–Wall–Ozawa method agreement with that method. Different mechanisms used compare this value. Also experimental data compared master curves. Analysis results suggested actual mechanism a D n deceleration type.
