Nano-TiO2/PVC paste composition films, which were prepared by ATBC, PVC paste resin and nano-TiO2, were studied in the irradiation condition of UV light. GPC, SEM, FT-IR and other special analyses were used to characterize the films. The results indicate that the degradation efficiency of nano-TiO2/PVC composition films is increased about 128.43% GPC test results indicate that after 720 h irradiation on the films, the Mn and Mw decrease 24.75% and 17.7% respectively, the surface morphology of nano-TiO2/PVC composition films shows many cracks and some cracking to pieces.
