A biologically degradable polyamide having a polyamide backbone of recurring amide units, said polyamide having attached thereto, in the a1 is a physiologically acceptable, hydrolyzable alkoxy group, having up to 18 carbon atoms, which is unsubstituted or substituted by physiologically acceptable side groups, or is a physiologically acceptable, hydrolyzable alkylamino or aralkylamino group, or is a hydroxyl group, and n is 3 or 4, a monomeric compound which is produced by esterification of aminoethanol with a dicarboxylic acid of the tricarboxylic acid cycle, and a monomeric compound of the formula Ib, [Figure] Ib in which R2 and R3, independently of one another, are hydrogen or methyl, and wherein the dicarboxylic acid (II) is at least one repeating unit of a dicarboxylic acid selected from the group consisting of a monomeric compound of the formula IIa, [Figure] IIa in which R4 is an alkyl group having 1 to 3 carbon atoms, and n is 1 or 2, a monomeric straight-chain, saturated or mono-unsaturated dicarboxylic acid having 2-10 carbon atoms, and a monomeric compound which is produced by esterification of at least one dicarboxylic acid of the tricarboxylic acid cycle with at least one diol of the formula IIb, [Figure] IIb in which R6 and R7, independently of one another, are hydrogen or a methyl group, and m is a number in the range 1 to 100, or by amidation with at least one diamine of the formula Ib, at least one of said diamine (I) and said dicarboxylic acid (II) supplying said functional group.
