Structurization in aqueous solutions of modified poly(vinyl alcohol)

Abstract

Dynamic light scattering from aqueous solutions of initial and modified poly(vinyl alcohol) with 5% carboxyl groups was studied depending on the concentration and the duration of aging at room temperature. Differences in the character of aggregation of macromolecules in these solutions and in (lie sizes of the clusters formed were determined. The aggregation process in the solutions of initial poly(vinyl alcohol) proceeds more rapidly and the sizes of macromolecular aggregates and clusters are substantially larger compared to the solutions of modified poly(vinyl alcohol).
