Abstract : The IR spectra of PVC specimens irradiated in vacuum by fast electrons at - 196 and 20 have been investigated. It has been shown that the irradiation is associated with dehydrochlorination leading to the formation of cis- and trans-vinyliene bonds, both isolated and conjugated. Terminal double bonds and methyl groups arise from main chain fracture. Irradiation at 20 causes the appearance of aromatic systems in the polymer. The nature of the structural changes depends on the irradiation temperature. The mechanisms of the processes occuring in the irradiation of PVC are discussed. (Author)
