Abstract:
Provided is a process for preparing a (meth)acrylic ester (F) of an N-hydroxyalkylated lactam, in which a cyclic N-hydroxyalkylated lactam (L): where the structural variables as defined herein, in the presence of at least one metal salt of C1-C10-alkoxides (A), is esterified with (meth)acrylic acid (S) or transesterified with at least one (meth)acrylic ester (D), in which the metal salt of C1-C10-alkoxides (A) used as a catalyst is added in the absence of solvents and completely at the start of the reaction.
