Nanoporous polymer networks with different composition are obtained by the 3D radical copolymerization of
N
-vinylpyrrolidone and triethylene glycol dimethacrylate in the presence of a branched copolymer that acts as a macromolecular template and a pore-forming agent. The processes of adsorption of polyvinylpyrrolidone, poly(methyl methacrylate), and polystyrene from their mixtures in chloroform by the
N
‑vinylpyrrolidone-based nanoporous polymer network and their desorption are studied. The molecular-weight distribution and composition of PVP–PMMA and PVP–PS mixtures (before and after adsorption) and macroobjects (after desorption) are studied by GPC and IR spectroscopy. A high selectivity of the nanoporous polymer network for the adsorption of polyvinylpyrrolidone from its mixture with nonpolar polystyrene is shown.
