FIELD: chemistry. n SUBSTANCE: present invention relates to a method of producing alkoxy-polyoxyalkylene(meth)acrylates. Described is a method of producing alkoxy-polyoxyalkylene(meth)acrylate, in which: a) at least one metal compound of formula MetOR 10 is taken, where Met denotes lithium, sodium, potassium, rubidium or caesium, and where R 10 denotes hydrogen or a straight or branched alkyl residue, b) at least one alcohol R 12 OH is added, where R 12 denotes a straight alkyl residue, with 1-18 carbon atoms or 2-(2-(2-methoxyethoxy)ethoxy)ethyl, where the molar mass of R 12 is less than that of alkoxy-polyoxyalkylenes, c) at least one alkylene oxide of formula (VI) is added and reacts with the metal compound of formula MetOR 10 , where residues R 11 denote, in each case independently from each other, hydrogen or a straight alkyl residue, and d) (meth)acrylic acid anhydride is directly added and reacts with the product from step c) in the presence of a stabiliser or a mixture of stabilisers. n EFFECT: simple and improved method of producing alkoxy-polyoxyalkylene(meth)acrylates. n 9 cl, 16 ex |
