The Effect of Heat Treatment Regimes of Polyphenylene Sulfides on their Thermal Properties

Thermal and thermo-oxidative degradation, as well as crosslinking and "curing" processes of polyphenylene sulfide, depending on the heat treatment regimes, have been studied using gas chromatography. The effect of sorbed water in the polymer on the processes of thermal and thermo-oxidative decomposition of polyphenylene sulfide is shown and the optimal modes of drying the samples are established.
