ABSTRACT:
(Meth)acrylic acid esters can be prepared by acid-catalyzed reaction of (meth)acrylic acid with alcohols in a water-immiscible solvent. After the esterification, the reaction mixture is washed with aqueous solutions having an alkaline reaction and then reacted at elevated temperature with carbodiimides. Acid numbers below 0.5 (mg of KOH/g of substance) are obtained in this way. (Meth)acrylic acid esters are used, for example, as reactive diluents or as comonomers.
