| Abstract: | The behaviour of poly-bis(p-tolylamino)phosphazene] under 60Co gamma irradiation was investigated in chloroform, carbon tetrachloride, benzene, toluene and tetrahydrofuran. Viscosity, average molecular weights and spectral changes were used to follow the degradation. The degradation mechanism was interpreted in terms of a combined interaction of the polymer molecule with dissolved oxygen and radiolysis products of the solvent. |
