Copolymerization chelate type monomers

The efficiency that this set of initiators showed for both types of polymerization reactions, and the displayed influence of the bound A,0-chelating ligand, led to testing for copolymerization of the two monomers. Impressively, the titanium pyridonate complexes led to a random copolymer with a nearly 1 1 ratio of monomers. These random copolymers have average molecular weights of 1.8-2.2X 10 g/mol with PDl values of 1.29-1.41. 

Type I A metal ion, a metal complex or metal chelate is connected with a linear or crosslinked macromolecule by covalent, coordinative, chelate, ionic or Ti-type bonds (Figure 1). This type I is realized by binding of the metal part at a linear, crosslinked polymer or at the outer or interior surface of an inorganic support. Another possibility uses the polymerization or copolymerization of metal containing monomers.
