Kinetics of the thermal degradation of anhydrous bisphenol‐A polycarbonate/alkali metal arylcarboxylate systems in the melt

Abstract

Abstract A kinetic study of the thermal degradation in the melt of bisphenol‐A polycarbonate in the presence of various anhydrous alkali metal arylcarboxylates is undertaken in order to assess the validity of the reaction mechanism previously established on a model system. The influence of the temperature, the concentration and the nature of the salt is studied. The results confirm the validity of the proposed kinetic model and suggest minor modifications to the reaction mechanism.
