Polyvinylchloride radiolysis

However, this does not result in the formation of sequences of conjugated double bonds as in the photodegradation of polyvinylchloride (see p. 379) or in the radiolysis of poly vinylacetate [13]. 

Demertzis and co-workers [48] carried out an in-depth study of the influence of gamma irradiation on the formation of solvent extractable radiolysis prodncts of flexible films and sheeting for food packaging. The packaging, which was made from PE, PP, polyethylene terephthalate (PET), PS, polyvinylchloride (PVC) and polyamide (PA), was subjected to Co irradiation at a dose of 44.0 kGy. Separation and identification of extracted compormds were carried out using GC-MS and compositional changes in the radiolysis prodncts quantified by calibration using MS detector response.
