Abstract

Thermal degradation behavior of blends based on a poly(ester urethane) and poly(ether sulfone) with or without poly(urethane sulfone) taken as a compatibilizer was investigated by thermogravimetric analysis under dynamic conditions. The theoretical mass loss curves were compared with the experimental ones in order to see the influence of blending on the thermal stabilities. The resulting data together with analysis of activation energies demonstrated that the presence of polysulfone caused a rise in thermal stability, interactions appear during degradation and the compatibilizer influences the thermal behavior of the studied blends.
