A research-based mechanism for cryostructuring aqueous solutions of polyvinyl alcohol, i.e., converting solutions from a fluid state into elastic bodies (cryogels), is proposed. In addition to the theoretical substantiation of the mechanism, experimental results of rheological and spectral studies of the cryogels obtained are also presented. An explanation is given for the significant difference between the cryostructuring temperature of an aqueous solution of polyvinyl alcohol and the melting temperature of formed elastic cryogels.
