Study of rheological properties of polyaniline compositions with polyacids

AbstractThis paper describes how the characteristic viscosity of polyaniline taken as a sample increases with the average increase in the high molecular weight fraction of polyaniline in the reaction medium. It was found that the intrinsic viscosity of the obtained polyaniline samples increases with an increase in the proportion of the average high molecular weight of polyaniline in the reaction medium. This effect can be explained with the binding of lithium ions to macromolecules and unfolding of coils of the polyacrylic acid chain. The unfolding of the coils can be explained by the electrostatic repulsion of ions bound to the polymers.
