Abstract: The coordination of the functionalities that may be
present either in the monomer or in the growing polymer chain to the
metal center is a key impediment in the development of new transition
metal-based catalysts for the insertion polymerization of polar monomers.
Several examples are discussed to illustrate this problem. Additionally,
it is shown that the reduction of the electrophilicity of the metal
center is one way to decrease this interaction.
