Abstract (en)
[origin: US2015232409A1] In a process for preparing (meth)acrylic esters (E) of polyalkoxy-containing alcohols which comprises reacting polyalkoxy-containing alcohols (P) of formula (I) where R1 is hydrogen, a hydroxyl group or a straight-chain or branched, saturated or unsaturated alcohol of 1 to 30 carbon atoms, R2 and R3 are each independently H or methyl, and m and n are each independently an integer between 0 and 100, with the proviso that m and n cannot both be 0, with a (meth)acrylic anhydride (A) in the presence of at least one basic catalyst (K) having a pKB value of not more than 7.0 and of at least one sterically hindered polymerization inhibitor, the reaction mixture is quenched with a C1-C6 alkanol after the reaction has ended.
