Abstract: In the production of polyacrylates (I) based on alkyl (alkyl)acrylate(s) in the presence of a starter composition containing an alkali ester enolate (II) and an organic aluminium compound (III), the starter composition contains an ester (IV) which is different from the monomers and has no acidic proton on the carbon atom in the alpha -position to the ester group. Also claimed are: (a) a starter composition containing (II), (III) and (IV); and (b) its preparation by (1) mixing alkyl and/or alkylaryl alkali compound(s) with (III), then (2) adding an alkyl alkylacrylate in an amount stoichiometrically equivalent to the alkali compound finally (3) adding (IV).
