Sorption ability of intergel system polymethacrylic acid hydrogel (gPMAA) – poly-4-vinylpyridine hydrogel (gP4VP) in relation to lanthanum ions is studied. Hydrogels mutual activation in an aqueous medium, particularly dependencies of swelling coefficient, specific electric conductivity and pH of water solutions are studied. Maximum activation of hydrogels occurs at gPMAA:gP4VP molar ratio 3:3. Maximum total binding degree of polymer chain in the intergel system is observed at the ratio gPMAA:gP4VP = 1:5. It has the value of 73.13 %, which is much higher than at initial hydrogels: gPMAA binding degree is 55.17 %, gP4VP – 55.00 %. The obtained results point to the fact that at this ratio there are significant changes of electrochemical, conformational and sorption degrees of initial macromolecules in intergel system.
