Thermodynamic Studies on Some Multicomponent Intermacromolecular Complexes of Varying Composition Involving an Acrylic Polymer, a Polyelectrolyte and a Nonionic Polymer

Abstract

The effect of composition on stability constant and related thermodynamic parameters (e.g., DH 0 and DS 0 ) have been determined for some multicomponent intermacromolecular complexes of varying composition involving poly(acrylic acid), poly(vinyl pyrrolidone) and poly(ethylene imine). The enthalpy and entropy changes of the systems with temperature have been interpreted in terms of destabilization of the various interacting forces involved in complex formation.
