✦ Synopsis

Thermal degradation of PVC in various solvents at 180 has been observed to be in the following order: benzonitrite > nitrobenzene > cyclohexanone > dioctyl phthalate > :~-bromonaphthalane > decahydronaphthalene. The effect has been explained on the basis of/3-eliminations of E~-type favoured by polar solvents. An inhibition in PVC degradation has been observed in nitrobenzene containing stationary hydrogen chloride gas. The deceleration in degradation by predissolved HC1 has been accounted for as a Mass Law effect.
