ABSTRACT OF THE DISCLOSURE: Copolymers consisting of (a) 39.9 to 99.9 molar percent of units of the general formula A, formed by a basic monomer selected among N-substituted acrylamideo, N-substituted meth- acrylamides and N, N-disubstituted acrylamides, (A) Image where R1 is H or CH3, R2 is an alkyl or alkoxyalkyl radical ha- ving from one to six carbon atoms and substituted or not with up to three OH groups, and R3 is H or R2 when R1 is H, or R3 is H when R1 is CH3; (b) 0.1 to 50 molar percent of units X formed by copolymerization with a monomer selected from the group compri- sing: Image , wherein R4 is hydrogen or methyl, R5 is a residue of p-nitro- phenol, 2,3,5-trichlorophenol, 8-hydroxyquinoline, N-hydroxy- succinimide or N-hydroxyphthalimide, and n = 0 to 4, Image , where in x = 2 to 10, Image , and Image , wherein the substituents R4 and R5 have the aforesaid meanings; and (c) 0 to 60 molar percent of units Z formed by copolymeriza- tion with a divinyl compound selected from the group comprising bis-acrylamides, bismethacrylamides, bis-acrylates, ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, 1,4- cyclohexyldimethyl dimethacrylate, 1,6-hexamethylene-bis-acryla- mide, 1,6-hexamethylene dimethacrylate, N,N-methylene-bis-acryla- mide, N,N-ethylene-bis-methacrylamide, tetraethylene glycol dis- crylate, tetraethylene glycol dimethacrylate, tetramethylene dis- crylate, 1,1,1-trimethylolethane trimethacrylate, 1,1,1-trime- thylolpropane triacrylate, 1,1,1-trimethylolpropane trimethacryla- te, diisopropylene glycol dimethacrylate, ethylidene diacrylate, ethylidene dimethacrylate, divinylsulfone and triacryloylperhydro- triazine. These copolymers an particularly useful for the bonding of biologically active compounds. Copolymers containing the divinyl component (c) are suitable for use as separation membranes or as packings for columns for the gel or affinity chromatography.
