Abstract

Polymers comprising a ligand containing a carboxylic acid group, optionally at least one ion of an element of the atomic numbers 21-29, 42, 44 or 57-83 as well as optionally cations of inorganic and/or organic bases, amino acids or amino acid amides are valuable complexing agents and complexes for diagnosis.
