Five kinds of aromatic polymers [polycarbonate(PC), polyarylate(PAR), polyetherimide(PEI), polysulfone(PSF), polyethersulfone(PESF)] were degraded at 380 Β° in vacuum. The molecular weights and molecular weight distributions of degraded samples were measured by gel permeation chromatography, using di
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
Bisphenol A polysulphone (PSF) and polyethersulphone (PESF) were photodegraded homogeneously at room temperature in an inert and a normal atmosphere. The average molecular weights and the molecular weight distributions of degraded samples were measured by means of GPC to evaluate the quantum yields
