Abstract Structural-mechanical strength and swelling of gels consisting of gelatin and potassium hyaluronate (PHY) or potassium protine-chondroitin-4-sulfate (PPCS) were shown to depend on the ratio between the components. With low concentrations of PHY and PPCS the minimum of structural-mechanical strength coincided with the maximum of swelling of the gels. In zones of neutralization of the positive electric charges of gelatin by macropolyanions, high structural-mechanical strength of the gels coincided with the minimum of swelling. In high concentrations of PHY, structural-mechanical strength and swelling of the gel became equal to the values characteristic of a gel consisting of gelatin only, but in high concentration of PPCS there was an additional parallel increase in this strength and in swelling of the gel.
