1 Introduction
Supermacroporous polymer cryogels are attractive materials due to their unique
heterogeneous structure composed of large interconnected pores that are filled with
solvent and surrounded by thin walls. Such a structure makes the diffusion of fluids
and species within the volume of cryogel easy and, thereby, facilitates mass and
heat transfer [1, 2]. Polymer cryogels are formed as a result of freezing of low or
high molar mass precursors (dissolved most often in water), crosslinking, and
subsequent thawing. A very important feature determining the success of
