## Abstract The anionic polymerization of methyl methacrylate (MMA) was carried out in the presence of ethyl Ξ±βlithioisobutyrate (Ξ±βLiEtIB)/quaternary ammonium salts (QAS) in toluene and tetrahydrofuran/toluene (vol. ratio 75/25) at β60Β°C. It was found that the tacticity of PMMA strongly depends on
