Abstract: A process for the living anionic polymerization of alkyl(meth)acrylic monomers, involving polymerizing the monomers in the presence of an initiator comprising a carbanion and a metal or nonmetal salt of perchloric acid. The initiator has the formula (I): wherein R1=a linear or branched alkyl group having one to six carbon atoms, R2=a phenyl or alkyl group having one to six carbon atoms, R3=a phenyl or an ester group and M+ is an alkali, alkaline earth metal or quarternary ammonium cation containing 1-8 carbon atoms in an alkyl group thereof.
