Process for preparing hydroxyalkyl(meth) acrylates using Lewis acid catalysts
摘要:
The present invention relates to a process for preparing hydroxyalkyl (meth)acrylates by reacting at least one compound A which contains at least one epoxide group with at least one compound B which contains at least one carboxylic acid group, wherein A and/or B also contains at least one (meth)acrylate group, in the presence of Lewis acid catalysts, each of which contains at least one directly bonded di(cyclo)alkylamino group.
