Density measurements of poly(acrylic acid) potassium salts (PAK) with different degrees of neutralization and water contents are presentea. The apparent partial molar volumes of polymer, V2, and the partial molar volumes of water, V1, were calculated from the densities. The values of V2 decreased with increasing water content and eventually leveled off. The values of V1, which at low water contents were much smaller than that of free water, increased with increasing water content and reached that of free water, showing consequently the appearance of free water. Before reaching the final value of free water, the data indicated the formation of primary and secondary hydration shells. The structure of primary, hydration was suggested to be of body-centered cubic coordination in which carboxyl oxygen atoms participate.
