| Abstract: | Molecular weights of PVC plastics , which containing non photo oxidative. containing rare earth carboxylate(RECar 3) and containing FeSt 3, were been determined by GPC before being illuminated and after. The results showed that both RECar 3 and FeSt 3 were efficient photosensitizer for degradable PVC ,but RECar 3 caused less cross link of PVC plastic than FeSt 3. |
