抄録

A series of metal alkoxides [M (Oi-Pr) n (M=Al, Sn, Ti, Zr, Sc) and Ti (OR) 4 (R=Me, Et, i-Pr, t-Bu, Ph) ] were examined as additives for rate enhancement and finer reaction control in the living radical polymerization of methyl methacrylate (MMA) with RuCl2 (PPh3) 3. All the additives induced a faster polymerization than in their absence and gave polymers with controlled molecular weights and narrow molecular weight distributions (MWDs) (Mw/Mn=1.1-1.3). Ti (Oi-Pr) 4 was the most effective in terms of the rate and the controllability and was effective in the synthesis of a high molecular weight polymer with a narrow MWD (Mn=100900, Mw/Mn=1.11). 1H NMR analysis showed that the added titanium alkoxide interacted with RuCl2 (PPh3) 3 to generate a more active catalyst.
