The effect of quantenary ammonium salts(QAS) on the reaction speed and structure of the product of dehydrochlorinated PVC (polyvinylchloride) and the relationship of dehydrochlo-rination reaction with temperature and time were studied by means of dehydrochlorination of PVC-QAS film in the solid phase. Butyl-ammonium salts (BAS) is found better than ethyl-ammonium salts (EAS) in catalytic property. As a result of experiments
the catalytic mechanism of the decomposition of QAS into tertiary amine was proposed.
