METHOD OF PRODUCING ALKOXY-POLYOXYALKYLENE(METH)ACRYLATES Russian patent published in 2012 - IPC C07C67/08 C08G65/34 

FIELD: chemistry.

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 MetOR¹⁰ is taken, where Met denotes lithium, sodium, potassium, rubidium or caesium, and where R¹⁰ denotes hydrogen or a straight or branched alkyl residue, b) at least one alcohol R¹²OH is added, where R¹² denotes a straight alkyl residue, with 1-18 carbon atoms or 2-(2-(2-methoxyethoxy)ethoxy)ethyl, where the molar mass of R¹² 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 MetOR¹⁰, where residues R¹¹ 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.

EFFECT: simple and improved method of producing alkoxy-polyoxyalkylene(meth)acrylates.
