In the light of polaron theory it is shown that, in the thermal dehydrochlorination (TDHC) of poly(vinylchloride) (PVC), the medium can, by its interaction with the double bonds existing in PVC, control the rate, the mechanisms of TDHC, the cis/trans configuration and the length distribution of conj...
