Abstract
The photochemical stability of polystyrene, PS, modified by small amount of poly(vinyl acetate), PVAC,(1–5% wt)has been investigated using Gel Permeation Chromatography(GPC). Photocrosslinking process of PS with PVAC samples was studied by estimation of insoluble gel content. PVAC caused improvement of mechanical properties of PS but UV-irradiation leads to their fast deterioration. Results indicate that dispersion degree of modifying component has a significant influence on the course of photochemical reactions in polymer composition.
