The specific focus of our interest is on understanding and ultimately improving the thermooxidative stability (TOS) of the PMR-15 polyimide system. We reasoned (by analogy to sterically hindered dioxetanes) that steric blocking should help stabilize the peptide linkage, forcing it to reclose rapidly and, thereby, improve its thermooxidative stability. It was for this reason that we explored the properties of polyimides containing the new dianhydride, 1, 4-phenylene bis(phenylmaleic anhydride). However, the TOS was significantly lower than PMR-15.
