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 thermal dehydrochlorination of model compounds of PVC has been investigated in the liquid phase in an inert atmosphere. Electrophilic catalysis and the effect of various solvents on this reaction have been studied. It has been found that the electron-accepting power of the reaction medium is the
## Abstract Crosslinked poly(vinyl chloride) (CPVC) samples with various extent of dehydrochlorination __x__, exhibiting a shape memory effect, were prepared. In order to determine the optimal structure for the shape memory effect, electron microscopy, dilatometry, differential thermal analysis (DT
