We have prepared a series of zinc(II), cadmium(II) and cobalt(II) complexes containing N’-aromatic substituted N,N-bis(1H-pyrazolyl-1-methyl)aniline derivatives. We have compared structural and chemical properties of these complexes for the catalyst of methyl methacrylate (MMA) polymerization The catalytic properties of zinc(II), cadmium(II) and cobalt(II) complexes toward the MMA polymerization in the presence of MMAO were investigated at 60 oC.
