Description: 
The products derived from thermo‐oxidation of poly(bisphenol A carbonate) (PC) and their related degradation pathways are investigated. PC degradation is carried out at 300 °C in air. The oxidized products are analyzed for the first time by using direct electrospray mass spectrometry (MS) and matrix‐assisted laser desorption ionization time of flight MS. Together with the formation of bisphenol A oligomers, several new structures containing biphenyl units, phenols, acetophenones, alcohols, acids, and xanthones molecules are detected. The use of thin films, instead of PC bulk, allows one to obtain precise information about mechanisms involved during thermo‐oxidative processes and to establish a new order of priorities among the renowned degradative reactions.
