    Abstract: Method for producing (meth)acrylic acid esters (E) of polyalkoxy group-containing alcohols by reacting polyalkoxy-group containing alcohols (P) of formula (I), where R1 represents hydrogen, a hydroxy group or a linear or branched, saturated or unsaturated, alcohol having from 1 to 30 C atoms, R
    2 , R
    3 represent independently of one another H or methyl, and m and n represent independently of one another a whole integer between 0 and 100, with the proviso that m and n may not simultaneously be 0, in the presence of at least one basic catalyst (K) having a pK
    B value not above 7.0, with at least one sterically hindered polymerization inhibitor comprising a (meth) acrylic acid anhydride (A), characterized in that following completion of the reaction the reaction mixture is quenched with a C
    1 -C
    6 -alkanol.
