A PROCESS FOR PREPARING ESTERS OF ETHYLENICALLY UNSATURATED CARBOXYLIC ACIDS

摘要

The present invention relates to a process for preparing unsaturated esters by azeo- tropically esterifying a) monohydric or polyhydric alcohols or b) polyesters which contain at least two hydroxyl groups per molecule and are the reaction product of polyhydric alcohols with mono- or dibasis, saturated or aromatically unsaturated carboxylic acids, with ethylenically unsaturated carboxylic acids in the presence of an acid catalyst and subsequently reacting the acid catalyst and any unesterified carboxylic acid groups with ethylenically unsaturated monoepoxy compounds.
