Novel substituted polyamides and process for producing them
Abstract
Abstract Novel substituted polyamides of the general formula ##EQU1## wherein A and B, which may be identical or different, are the hydrocarbon backbone groups of the formula --(CH 2 ) n --, where n is an integer, R 2 and R 3 are the residues of an aldehyde R 2 --CHO or of an isocyanide R 3 --N.tbd.C, where R 2 and R 3 are aliphatic, aromatic or heterocyclic residues of the respective aldehyde or isocyanide, or where R 3 is a chromophoric moiety. R 2 and R 3 can be substituted, and amongst the possible substituents there may be R 3 designating --(CH 2 ) n --NHCO--CHR 2 --N(CO)(R 4 )--X, where R 4 is the residue of a monocarboxylic or dicarboxylic acid and X is the lysyl residue of a protein, which may be biologically active, or the residue of a low-molecular weight compound containing a primary amine moiety. Preferred polyamides are various types of nylons. Amongst proteins chemically bound to the polyamide there may be mentioned enzymes, antibodies and peptide hormones. When R 3 is a chromophoric moiety, the product is a chemically dyed polyamide. The invention relates also to a process for the production of such novel substituted polyamides.
