Abstract Physicochemical parameters of cation-exchange resin K-12/14 having acrylic, methacrylic acid and TEGDMA units have been estimated at different ionization degree of carboxylic groups. The change of swelling and sorption increase rate at α=0.2 has been found. Mechanical test in compression of resin samples also show sharp change at this ionization degree. The results obtained have been discussed with the view of polymer network structure change.
