| Abstract The densities of aqueous solution of poly (vinyl alcohol)with molecular weight (125000 g.mol-1) have been determined up to a weight molality of 0.0487 over temperature range 298.15-328.15 K. From these data, the apparent specific volume of the solute and the partial specific volume of the solute and solvent were calculated. The specific excess volume of the solution and the coefficients of the virial expansion of the excess property were evaluated and interpreted in terms of solute-solute and solute-solvent interaction. | ||
