Abstract: A process is disclosed for producing reaction mixtures including homopolymers, copolymers or block copolymers, and for producing homopolymers, copolymers and block copolymers containing acrylates and/or methacrylates. The process is characterised in that olefinically unsaturated compounds which are not derived from acrylate or methacrylate are used as solvents or as solvent components.

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).

Abstract: The invention concerns a process for preparing rubber-modified moulding compounds, characterized in that: a1) a mixture (A) comprising acrylate or methacrylate derivatives or acrylate and methacrylate derivatives and a solvent, optionally containing olefinically unsaturated compounds which are not acrylate or methacrylate derivatives, is anionically polymerized; or that a2) acrylate or methacrylate derivatives or acrylate and methacrylate derivatives are sequentially anionically polymerized to form block copolymers in the presence of a solvent which optionally contains olefinically unsaturated compounds; and b) the reaction mixture obtained according to a1) or a2) or a1) and a2) is subjected to a radically initiated polymerization process, optionally after the addition of further unsaturated compounds.
