Interpenetrating networks based on acrylic hydrogel and collagen were obtained by the method of free-radical polymerization. The effect of the degree of neutralization of acrylic acid and the temperature of synthesis of acrylic composites on the duration of the onset of gelation, of the obtained ratio of polymeric materials was studied. A decrease in the duration of the onset of gelation, with an increase in the degree of neutralization of acrylic acid from 0.6 to 1 and an increase in temperature from 25 to 45 °C was shown. During the work, the kinetics of swelling of the obtained samples on the basis of a pseudo-second order model and a mathematical model in distilled water, saline and phosphate-buffered saline was investigated. It was shown that synthesized polymer samples upon solvent sorption are described by Fick’s low diffusion (n <0.5)
