Summary A novel trifunctional samarium enolate, prepared in situ by the reduction of 1,3,5-tris(2-bromoisobutyroyloxymethyl)benzene with SmI2, has proven to initiate the polymerization of methyl methacrylate (MMA). Characterization of the polymer by 1H NMR and GPC clearly supported the formation of a star-shaped tri-armed poly(MMA). The resulting star-shaped poly(MMA) possessed narrow molecular weight distribution, and its molecular weight agreed well with the theoretical value, which reveals the quantitative initiation efficiency.
