Abstract The paper deals with aging of concentrated poly(vinyl alcohol) solutions prepared from polymer samples which, prior to dissolution, were heated at various temperatures in an aqueous suspension or in the powder state. The effect of preheating is discussed on the basis of changes in viscosity and normal stress difference, measured during aging.
