Preferred capolymers are methacrylic acid-alkyl methacrylate-alkyl acrylate, methacrylic acid-alkyl methacrylate, alkyl acrylate-methacrylic acid, alkyl acrylate-methacrylic acid-alkyl acrylate, alkyl acrylate-methacrylic acid-2-methyl-5-vinylpyridine and dialkylaminoalkyl methacrylate-alkyl methacrylate. The immobilized enzyme has a high activity and can dissolve even in an organic solvent or in a solution containing an organic solvent.
