Thermal degradation of chemically modified polysulfones

Thermal degradation of chemically modified polysulfones

The thermal stability of some known (bromomethylated, carboxylated, brominated, nitrated) and novel (tertiary amine) polysulfone (PSU) derivatives has been studied by thermogravimetry (TG). The thermal decomposition products have been identified by various coupled mass spectrometric (MS) methods. Fr...

Zusammenfassung:The thermal stability of some known (bromomethylated, carboxylated, brominated, nitrated) and novel (tertiary amine) polysulfone (PSU) derivatives has been studied by thermogravimetry (TG). The thermal decomposition products have been identified by various coupled mass spectrometric (MS) methods. From these data, the possible decomposition mechanism was deduced.
