Polyvinyl alcohol (PVA) gels, prepared by freezing-thawing technique were studied. PVA water solutions were exposed to 1 - 3 subsequent cycles of freezing (12 h at -20oC) followed by thawing (12 h at 20oC). Values of water content (weight and volume fraction) and degree of swelling at the equilibrium state were determined. Values of average molecular weight of polymer chains between cross-links Mc (using Flory-Rehner approach) were calculated.
