| Abstract: | Arrhenius equation which showed the relationship between the oxidation induction time(OIT) and the aging temperature was established based on OIT measured under different temperature by using differential scanning calorimetry(DSC)accelerated aging test method,and the OIT of polypropylene at different temperature was quickly estimated by using Arrhenius equation.The results showed that the estimates based on Arrhenius equation was effective,which was a good method for screening antioxidant formula. |
