Cascade polymers, processes for the preparation thereof and pharmaceutical compositions containing the same

摘要

Cascade polymers containing complexing ligands, if desired at least five ions of an element having an atomic number of from 21 to 29, 39, 42, 44 or 57 to 83, and if desired cations of inorganic and/or organic bases, amino acids or amino acid amides, are valuable complexing agents and complexes for diagnostics and therapy.
