摘要：

Injection moulded test specimens of polyamide 6,6 have been subjected to ageing in ambient atmosphere at temperatures ranging from 100 to 130 degrees C for different times. Skin-core oxidation was observed and evaluated by infrared spectroscopy in terms of carbonyl index depth profiles and by imaging chemiluminescence as peroxide depth profiles. The oxidation depth profiles determined by the two techniques showed good agreement with respect to ageing time and temperature. The oxidation depth was shown to decrease with increasing ageing temperature. The results clearly indicate a diffusion-controlled oxidation process. (C) 1997 Elsevier Science Limited.
