Dynamic Mechanical Properties of Aromatic Polyamideimide Degraded in NO2 Atmosphere

The degradation of aliphatic polyamide as nylon 66 in an NO2 atmosphere has been investigated by Jellinek,1 based on the mole-cular weight changes determined by the change of solution viscosity. The aromatic polyamideimides are also accessible to NO2, but are slightly soluble in polar solvents as N-methyl pyrrolidone(NMP) and the solutions obtained are not readily stable to estimate the degree of degradation from the usual viscosity measurements. Therefore, we investigated the degradation of aromatic polyamideimide by following the change of dynamic mechanical properties in an NO2 atmosphere.
