A soluble polyimide (PI2080) was thermally and thermo-oxidatively degraded. Crosslinking was found to proceed under both conditions. Crosslinking densities of degraded samples were estimated before and after the gel point by gel permeation chromatography and by a new method using thermomechanical an
