The binding strength of metal-complexes can be varied very easily by changing the metal-ligand combination. Therefore, metal complexes could be utilized for the design of self-healing polymers. For this purpose, terpyridine moieties were incorporated into the side chain of a linear polymer (i.e. polymetharylates, polybutadienes). The following crosslinking reaction leads to metallopolymer networks which feature self-healing properties. Furthermore, different parameters (e.g., metal ion, crosslinking density, counter ion) were varied in order to understand the basic self-healing mechanism. Thus, we used different cadmium salts for the crosslinking reaction in order to analyze the molecular structure. Furthermore, the polymer backbone was varied from methacrylic polymer to a polybutadiene. The different obtained substructures have a great influence on the self-healing performance of the metallopolymer networks.[1]1.) S. Bode, R. K. Bose, S. Matthes, M. Ehrhardt, A. Seifert, F. H.
