Description

Samples of pure and commercial powder PVC was irradiated with 0-100 kGy γ radiation. The visible yellowness observed in this samples occurred when they were irradiated as of 50 kGy. The Tg values obtained from DSC showed the plasticizers influence in the polymeric mobility. The IR spectra showed the presence of C=O in the no irradiated pure PVC, originated by the polymerization process. The addition of plasticizers favors the radiolytic oxidation.
