Process for preparing esters of (meth) acrylic acid

摘要

The present invention relates to a process for preparing (meth)acrylic acid esters by 1) reacting hydroxyl group-containing polyethers, polyesters or polyester ethers with (meth)acrylic acid in the presence of an acid esterification catalyst and a solvent to form (meth)acrylic acid esters, and 2) reacting the acid esterification catalyst acid and unreacted (meth)acrylic acid with a compound containing two or more epoxide groups in the presence of the solvent used in step 1).
