Anionic polymerizations of methyl methacrylate, n-butyl methacrylate and tert-butyl methacrylate with 1,1-diphenylhexyllithium in THF at 195 K were performed. By characterizing the resultant polymers, the controllable limits of molecular weight and molecular weight distribution were examined. Tert-butyl methacrylate gave a polymer with a high molecular weight (1.8 x 105) and narrow molecular weight distribution (Mw/M . = 1.0 7). A well-defined block copolymer of'tert-butyl methacrylate with styrene or c~-methylstyrene was obtained by intermediate addition of l,l-diphenylethylene.
