Thermal degradation of poly(arylene sulfide sulfone)/N-methylpyrrolidone crystal solvate

The thermal degradation of poly(arylene sulfide sulfone)/N-methylpyrrolidone(PASS/NMP) crystal solvate was studied by thermogravimetric analysis(TGA) and was compared with pure PASS in order to determine the way in which the formation of the crystal solvate affected the thermal properties of the polymer.The activation energy of the solid state process was determined using Kissinger's method,which does not require knowledge of the reaction mechanism(RM),to be 174.18 kJ/mol which was lower than that for pure ...
