Abstract

Polyimides are widely used in large number of technological applications, especially, in building modern aircraft structures, due to their unique physical and chemical properties and ease of fabrication. However, their oxidative degradation during long term usage is a serious concern in practical applications at varying temperature. We address here the thermal oxidative degradation of polyimides at a molecular level, considering PMR-15 as an example, employing first principles quantum chemical calculations. In particular, this work focuses on the oxidation mechanism of diphenylmethane part, which is one of the most susceptible sites within the polymer for oxidation.
