Light-scattering studies of aggregation in aqueous solutions of poly(vinyl alcohol co-vinyl acetate) copolymer

Abstract

Light-scattering studies are presented for a series of aqueous solutions of a poly(vinyl alcohol co-vinyl acetate) copolymer, of varying concentration, over the temperature range 5–30 °C. The data indicate the presence of an aggregation process which occurs over a narrow concentration range; the data further indicate that the temperature-dependent conformational change in the macromolecule, which has been reported previously, is also reflected in the aggregation process.
