✦ Synopsis

A~tract--The degradation of copolymers of vinyl 36CI-chloride and methyl methacrylate has been studied using film samples, slow heating rate and high vacuum conditions. Volatilization has been followed using thermal volatilization analysis and radioactive assay of methyl chloride and hydrogen chloride. By carrying out duplicate experiments with and without an ice trap at -lOft, it is possible to measure methyl chloride alone and both products, respectively, so that each product can be estimated. Yields have been found to agree well with those predicted from sequence distribution calculations. Some differences in behaviour compared with earlier work using powder samples and nitrogen flow conditions are discussed.
