Abstract: Thermal degradation of emulsion statistical copolymers of acrylonitrile and vinylidene chloride and/or terpolymers with glycidyl methacrylate or glycidyl acrylate was carried out in the temperature range from 25 to 450°C in nitrogen and was studied by conductometry and by gas chromatography. We have found that epoxy groups of the third component of terpolymers favourably affect the beginning of dehydrochlorination because they bind the first amounts of the releasing hydrogen chloride. With decreasing molecular mass of a sample, the rate of the HCl abstraction considerably increases. With samples of the lowest molecular masses, almost complete dehydrochlorination occurs.
