This article deals that the rare earth metal complexes along with Al ( i ‐Bu) 3 can catalyze the polymerization of methyl‐methacrylate (MMA) into high molecular weight poly(MMA) along with narrow molecular weight distributions (MWD). A typical example was mentioned in the case of {Cp(Cl) Sm‐Schiff‐base(THF)} which expresses maximum (conv. % = 55.46 and M n = 354 × 10 3 ) efficiency along with narrow MWD (M w /M n < 2) at 60°C. The resulting polymer was partially syndiotactic (>60%). The effect of the catalyst, temperature, catalyst/MMA molar ratio, catalyst/Al( i ‐Bu) 3 molar ratio on the polymerization of MMA at 60°C were also investigated.
