Abstract:	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°C; 6 h. Polymethyl methacrylate (PMMA) with 80% conversion, 7.2×10⁵ viscosity-average molecular weight and 60.5% syndiotacticity was obtained. This complex has also been shown to play an important role in scavenging $O\mathop \cdot \limits_2^ -$ .

Keywords:	novel copper complex Schiff base catalytic activity scavenging effect of O- 2
