Abstract:

The dilute solution viscometric behavior of polym-phenylene isophthalamide dissolved in LiCldimethylacetamide was studied. Important aspects of this investigation included interactions between dimethylacetamide and LiCl, polymer-polymer association, and the capability of polym-phenylene isophthalamide to become a polyion when dissolved in LiClDimethylacetamide. Counterion interaction with the polyion and the ability to control the ion concentration gave rise to interesting variations in the hydrodynamic volume of polym-phenylene isophthalamide leading to a maximum in its intrinsic viscosity as a function of LiCl concentration.
