Polyvinyl alcohol (PVA) was esterified by formic acid, acetic acid and propionic acid in the homogeneous system contained water using hydrochloric acid as catalyst and the surface tension of these esterified PVA was measured. The lowering of the surface tension with esterified PVA were great in the order of formic acid<acetic acid<propionic acid. It was presumed that the surface chemical properties of the aqueous solution of partially saponified polyvinyl ester became more active with increase in the hydrophobic property of the ester group, if the residual ester content and the distribution of ester groups in a polymer chain were the same.
