A macromolecular adenine derivative containing at least one unity having the general formula: <IMAGE> wherein, n is 1, 2, 3 or 4; the radical: <IMAGE> is derived from an adenine derivative wherein the amino group in position 6 in the adenine nucleus is functional; and the nitrogen atom, N<, belongs to a macromolecular compound containing one or more primary or secondary amine groups, is prepared by condensing the functional adenine derivative with a polymer containing one or more primary or secondary amine groups in the presence of a carbodiimide. These compounds are useful in affinity chromatographies or as unspreading co-enzymes. |
