A novel dinuclear copper complex with tetraglycol aldehyde-phenylalanine Schiff base has been synthesized. It was characterized and formulated as [Cu2L(NO3)]NO3 by elemental analysis, magnetic susceptibility, TG-DTA, IR, EPR and 1H NMR spectra. The obtained complex can be used as a good catalyst for the polymerization of methyl methacrylate (MMA). The optimum polymerization conditions are: MMA/catalyst = 500 (molar ratio); [catalyst] = 7.5×10?3 mol·L?1; dioxane as solvent; 80 ℃; 6 h. Polymethyl methacrylate (PMMA) with 80% conversion, 7.2×105 viscosity-average mo- lecular weight and 60.5% syndiotacticity was obtained. This complex has also been shown to play an important role in scavenging O2i .
