This review summarizes the progress made in the last eight years on the synthesis and use in catalysis of polymer supported metal complexes obtained by co-polymerization of metal-containing monomers (MCMs) with suitable co-monomers and cross-linkers. These materials are divided into four important classes: microporous organic polymers, molecularly imprinted polymers (MIPs), macropouros organic polymers, polymers obtained by ring opening metathesis polymerization (ROMP). Although the MIPs have essentially a macroporous structure, they constitute a separate group of catalysts for their peculiar way of synthesis. The discussion focuses on the efficiency and reusability of all these potentially recoverable catalysts.
Keywords: Metal-containing monomers, Porous polymers, Supported metal catalysts.
