Abstract:
Process for preparing an alkoxypolyoxyalkylene (meth)acrylate in which a) a metal alkoxide MetOR10 is initially charged, b) an alkylene oxide of the formula (IV) is added and reacted with the metal alkoxide and c) (meth)acrylic anhydride is added directly and reacted with the reaction product from step b). Appropriately, in step c), a stabilizer mixture is added which comprises, for example, the following components I. at least one compound of the formula (I) II. at least one compound of the formula (IIa or IIb) or of the formula (IV) III. at least one compound of the formula (V)
