Polyurethane (PU) gels with different crosslinking density and sequential semi-interpenetrating polymer network (semi-IPN) hydrogels based on them are synthesized. Natural polymers such as gelatin, carboxymethylcellulose (CMC), and poly(2-hydroxyethyl methacrylate) have been used as the second component. It is established that, with increasing the molecular mass of segments between two network junction points (Mc) of the initial PU network, the content of linear components in semi-IPNs increases. The degree of maximum swelling for the initial PU networks in water and in water solutions of gelatin, CMC, and in НЕМА and the content of the equilibrium water and bound water in PU and semi-IPN hydrogels symbatically depend on Mc of the initial PU networks.
