Subsequently, question is, why polyvinyl alcohol is soluble in water? Poly(vinyl alcohol) (PVA) is a watersoluble polymer whose water solubility depends on itsdegree of hydrolysis, molecular weight, and tendency to hydrogenbond in aqueous solutions. PVA exhibits both upper and lowercritical solubility temperatures and can be readilysolubilized in water.
