Translational diffusion in 96% H2S04 and intrinsic viscosity of poly(naphthoy1eneimide benzimidazole) (PNIB) have been investigated in different stages of its degradation in solution in the temperature range from 65 to 120OC. The degradation rate constant k has been determined from the change in mol
