The kinetics of the early stages of thermal degradation below 1% dehydrochlorination of emulsion-polymerized poly(vinylidene chloride) (PVDC) is studied by the variation of the pH value of potassium hydroxide aqueous solution between 160 and 190Β°C in the presence of air and other gas streams.

β¦ Synopsis
The thermal dehydrochlorination of PVC has been examined on some samples prepared by fractionation of a commercial PVC, and some other samples obtained by polymerization at different temperatures. The results disagree with the concept of a continuous dehydrochlorination from one side to the other of the chain, that necessitates initiating structural anomalies in the macromolecule itself.

An emulsion, poly(vinyl chloride) (PVC), was analyzed for its components and was used in the preparation of flexible PVC plates utilizing sol-gel processing technology. PVC contained an ether-soluble fraction having carboxylic acid carbonyl groups, a tetrahydrofurane (THF)-insoluble fraction having
