By studying cross-linking of poly-N-vinylpyrrolidone [Mn=1×104 and 4×104] with N,N`-methylene-bis-acrylamide there were obtained water-swelling gel-forming polymers. Also was studied immobilization process of trypsin in polymer gels and Co(II), Cu(II), Ni(II) metal gel-complexes in polymeric gels. It was found that the amount and activity of immobilized trypsin gel carriers based on poly-N-vinylpyrrolidone less compared to the amount and the activity of immobilized trypsin gel carrier cross-linking copolymer of N-vinylpyrrolidone with arabinogalactan from cherry gum. The immobilization mechanism of trypsin into polymer gels investigated by FTIR and 1H NMR spectroscopy.
