| titleOfInvention | Cobalt (II) complex catalyst for polymerization of monomers |
| abstract | New Cobalt (II) nitrilomethylidyne dipyrrole complexes such as Cobalt (II) 2,2'-[trimethylenebis(nitrilomethylidyne)]-dipyrrole, Cobalt(II) 2,2'[o-phenylenebis(nitrilomethylidyne)]-dipyrrole and their basic ligand complexes are effective catalysts for molecular weight control in acrylate/methacrylate polymerization. The Cobalt (II) complex of a nitrilomethylidyne dipyrrole comprises the structure: <IMAGE> where R is a diradical selected form trimethylene bis-, o-phenylenebis, or ethylenebis. The process comprises polymerizing monomers, especially including methacrylic monomer or methacrylic/acrylic monomer, in the presence of azo initiator and between 0.0001% and 0.01% of Cobalt (II) 2,2'-[trimethylenebis (nitrilomethylidyne)]-dipyrrole and/or Cobalt (II) 2,2'-[-phenylenebis (nitrilomethylidyne]-dipyrrole complexes to produce low molecular weight acrylate polymers and copolymers. |
