Low-crystalline polypropylene films (PP) were irradiated with different doses of γ-radiation (0, 1, 2.5, 5, 7.5 and 10 Mrad). Differential scanning calorimetry, (DSC), wide-angle X-ray diffraction (WAXD) and FT-IR measurements were used to study the effects of γ-radiation on crystallinity, crystalline structure and thermal changes. It was found that crystalline structure, thermal behavior and crystallinity significantly changed with γ-irradiation. The crystallinity changes mainly depend on γ-irradiation dose, chain scission and crosslinking. The rise in crystallinity was found to be limited and related to chain scission. However, the reduction was accompanied by formation of crosslinking.
