This thesis mainly studied the antioxidant 1010, antioxidant 1076, antioxidant 168 modification of PP polymer materials, through the yellow index before and after irradiation tests we can make that antioxidant 1010 and antioxidant 1076 can improve the irradiation resistance of PP; through the test of mechanical properties can be concluded that mechanical performance, though there are differences before and after irradiation, but the change is not big; Based on the thermal analysis of the sample before and after the irradiation can draw a conclusion that samples of thermal stability of slightly decreased after irradiation, crystallization temperature rise, crystallinity rise.
