Paper Abstract

The photo-oxidation of certain polyimides has been found to be extremely efficient provided that the photolysis is conducted in the presence of oxygen. The apparent rate of decomposition depends on the chemical composition of the components composing the polyimide backbone as well as the spectral properties of the light source. In the case of polyimides which are made from a hexafluorinated dianhydride and a hexafluorinated diamine, the photo-oxidation process is extremely rapid. The photolysis mechanism is quite complicated, but analysis of model compound photochemistry by conventional methods indicates that a variety of products, which themselves are photolabile, are generated in the primary photochemical process.
