E-mail:
In the solution polymerizations of methyl methacrylate with (α-diimine)nickel(II)/methylaluminoxane (MAO), we observed effects of the position of two methyl substituents in the ligand on both the activities of the catalysts and the polymer microstructure. α-Diimine nickel(II) catalysts gave syndiotactic-rich poly(methyl methacrylate) with high molecular weight and narrow molecular weight distribution.
Keywords:late transition metals;methyl methacrylate;ligand structure variation;microstructure.
