  • Publication number: 20100113725
    Abstract: A process for preparing (meth)acrylic esters (F) of N-hydroxyalkylated lactams, in which cyclic N-hydroxyalkylated lactams (L) in which R1 is C1-C5-alkylene, or C2-C20-alkylene interrupted by one or more oxygen and/or sulfur atoms and/or one or more substituted or unsubstituted imino groups and/or by one or more cycloalkyl, —(CO)—, —O(CO)O—, —(NH)(CO)O—, —O(CO)(NH)—, —O(CO)— or —(CO)O— groups, where the radicals mentioned may each be substituted by aryl, alkyl, aryloxy, alkyloxy, heteroatoms and/or heterocycles, with the proviso that R1 must not have any atom other than a carbon atom directly adjacent to the lactam carbonyl group, R2 is C1-C20-alkylene, C5-C12-cycloalkylene, C6-C12-arylene, or C2-C20-alkylene interrupted by one or more oxygen and/or sulfur atoms and/or one or more substituted or unsubstituted imino groups and/or by one or more cycloalkyl, —(CO)—, —O(CO)O—, —(NH)(CO)O—, —O(CO)(NH)—, —O(CO)— or —(CO)O— groups, where the radicals mentioned may each be substituted by aryl, alkyl, aryloxy, al

  • Publication number: 20100004462
    Abstract: A process for preparing (meth)acrylic esters (F) of N-hydroxyalkylated imidazoles, wherein N-hydroxyalkylated imidazoles (I), in which R1 and R2 may each independently be hydrogen or C1-C20-alkyl, R3, R4 and R5 are each independently hydrogen or C1-C20-alkyl, C1-C20-alkylcarbonyl, C2-C20-alkenyl, C2-C20-alkenylcarbonyl, C2-C20-alkynyl, C2-C20-alkynylcarbonyl, C3-C15-cycloalkyl, C3-C15-cycloalkylcarbonyl, aryl, arylcarbonyl, a heterocycle or a halogen atom, and m and n are each integers in the range of in each case from 0 to 20, where m and n cannot simultaneously be 0, and in which the particular units bracketed by the variables m and n are present in any sequence, and in which, in the case that m?2, the R1 and R2 radicals are in each case independent in the particular units, in the presence of at least one catalyst (K), are esterified with (meth)acrylic acid (S) or transesterified with at least one (meth)acrylic ester (D).
