Abstract

By using dichloromethane as a polymerization solvent, syndiotactic-specific polymerization of methyl methacrylate with t-BuLi in the presence of large excess of tributylaluminum at –78 °C proceeded more rapidly than in toluene and gave st-PMMA (rr = 90%) with narrow molar mass distribution. This method allows us to prepare st-PMMA with molar mass up to 350 × 103 in 48 h.
