The possibility of creating hydrogels of a new lamellar-chain type in the framework of in-creased rigidity on the basis of ternary aqueous solutions of polymeric and oligomeric molecules has been considered. A hypothetical model of such a framework whose structural elements are oligomeric lamellas and polymer chains is proposed. These elements are connected, because the ends of the polymer chains are embedded into the pores of lamellas. A formula for the free energy of such a system is obtained. It is shown that an increase in the polymer concentration should lead to a mutual approach of the lamellas. This conclusion is consistent with the results of a small-angle X-ray scattering experiment in which ternary aqueous solutions with various concentrations of a polymer (polyethylene glycol) or an oligomer (sodium dodecyl sulfate) are studied.
