Macromolecular metal complexes formation constants

The formation of type II metal-containing macromolecules obtained by the reaction of bi/multifunctional low molecular weight metal complexes with another bi/multi-functional ligand can be evaluated by usual rate constants, equilibrium and kinetics as known for polycondensation or polyaddition reactions in macromolecular chemistry. Increasing insolubility results easily in chain termination and formation oligomers. 

In classic coordination chemistry the parameter n is known as the formation function, showing the number of functional groups directly bound with metal ions, whereas in the coordination chemistry of macromolecular complexes this parameter corresponds to the average number of functional groups which are excluded from the total number of ligands for binding of one metal ion. Moreover, for complexation of MX with cross-linked polymers the total concentration of macroligands is constant and does not depend on the dilution of the suspension in a solvent.
