For the Schulz broad distributions with initial weight-polydispersity from 2 to 10, the correlation between the intrinsic viscosity and the degradation degree, DD = ln(M,,JM,,), has been found as the following equation system: ln[v] = 1n[qloa(ln Po -In P + DD); P = P F + (Po -P F ) X exp((So -1.43)(

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
