Abstract

The method of pyrolysis gas chromatography and thermovolumetric thermal analysis has been used for the investigation of polyamic acid-poly-N-vinylpyrrolidone and polyinude-poly-N-vinylpyrrolidone mixtures in helium. The products of thermal degradation have been identified. Data of analysis of gaseous and liquid degradation products for individual polymers and mixtures indicate that the mechanism of thermal degradation of polyimide changes when poly-N-vinylpyrrolidone is introduced into the mixture. This change is caused by the existence of the polymer-polymer interaction between the components of the mixture.
