摘要：

The present work was concerned with the study on relationship between the migration level of BPA and thermal-oxidative aging degree of PC used as food and packaging materials. It was indicated that with the increasing of thermal-oxidative aging time, the migration level of BPA increased. The migration level was far beyond the GB/T5009.99-2003 (China). Variation of phenolic hydroxyl absorption intensity in ER. spectra and the maximum absorption wavelength red shift of benzene in UV-Vis spectra indicated the same law; Initial weight loss temperature and maximum weight loss rate temperature of PC after thermal-oxidative aging were reduced by 1-2 degrees C and 3-5 degrees C respectively, and the thermal stability declined.
