The in situ themo-oxidative degradation of ABS-copolymers, initiated by di-benzoyl peroxide (BP) has been followed by chemiluminescence (CL) measurements. When conducted in the presence of an antioxidant it turns to a quick mean of antioxidant efficiency evaluation. ABS-copolymer containing antioxidants of various classes such as Irganox 1076, Irganox 565, trisnonylphenyl phosphite and dialkyl-thio-dipropionate was tested. The study has been carried out on the CL signal of the hydroperoxides in the SAN phase produced by BP initiated oxidation or processing. The best protecting efficiency was found for Irganox 565 and trisnonylphenyl phosphite. The results were confirmed by impact strength testing. The conditions for a correct antioxidant efficiency evaluation are discussed. |
