Abstract.
The ABS degradation was investigated after thermal- (80oC) and photo-oxidative ageing (ASTM G53 and G24). These conditions were selected to simulate a car interior and the ABS lifetime weatherability. ABS changed were chracterised by mechanical properties, melt flow index, carbonyl index (FT-IR), yellowing index and macro-photography of impact fracture.The results showed that each tehcnique gives a characteristically answer for the ageing method. Thre multivariate analysis provided the degradation view as a function of the ageing method.
