Abstract
In this research, the thermo-oxidative aging properties of PC/ABS with different content of antioxidant 1010 were studied. The ΔE value of the sample with 1wt% antioxidant 1010 was 35.3% lower than that without antioxidant before and after 500h aging. After aging for 500h, the elongation at break and impact strength of samples with 1wt% antioxidant 1010 decreased by about 76% and 42% respectively, which were 8% and 5% higher than those without antioxidant. The results of ATR-FTIR spectrum shown that antioxidant 1010 reduced the degradation of rubber phase (PB) in ABS caused by thermo-oxidative aging.
