Coordination-insertion copolymerization of polar vinyl monomers by palladium catalysts.

Random incorporation of polar functional groups into polyolefins and polyketones along with the precise control of incorporation ratios and polymer microstructures is one of the most significant challenges in polymer chemistry. For such a purpose, late-transition-metal complexes are often employed as a catalyst for the copolymerization of polar vinyl monomers, because of their high functional group compatibility. This account describes our contribution to the development of coordination-insertion copolymerization of polar vinyl monomers by palladium catalysts. In particular, the use of palladium/phosphine-sulfonate catalysts enables to incorporate various polar vinyl monomers into polyolefins and polyketones.
