【Abstract】 The structure of heat treated polyphenylene sulfide（PPS） in the presence of air both in the molten state and solid state was studied by FTIR. The heat treated ppS in the molten state shows a 1162 cm^-1 band which is a characteristic one for the thermo-oxidative crosslinking structure and that in the solid state shows a 819 cm^-1 band which indicates the degree of crystallinity raising. The many other bands of the heat treated PPS were discussed.更多还原
