Polymerization of Methyl Methacrylate with Ni(II) <i>α</i>‐Diimine/MAO and Fe(II) and Co(II) Pyridyl Bis(imine)/MAO

Abstract

Abstract Polymerizations of methyl methacrylate with ( α ‐diimine)nickel(II)/methylaluminoxane (MAO) and (pyridyl bis(imine))iron(II) and (pyridyl bis(imine))cobalt(II)/MAO are reported. Effects of structural variation of the ligand on the activities of catalysts and polymer microstructure are described. The catalyst systems gave syndio‐rich poly(methyl methacrylate). The α ‐diimine system showed much higher activity than the pyridyl bis(imine) systems under similar polymerization conditions. magnified image
