Imposed Polyelectrolyte Behavior of Poly(m-Phenylene Isophthalamide) in LiCl/Di-Methylacetamide.

Abstract

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