Abstract

Cascade polymers, containing complex-forming ligands, optionally at least five ions of an element of atomic numbers 21-29, 39, 42, 44 or 57-83, as well as, if desired, cations of inorganic and/or organic bases, amino acids or amino acid amides, are valuable complexing compounds and complexes for diagnostics and therapy.
