Abstract: PROBLEM TO BE SOLVED: To provide a simple process for producing an ester of α,β- monoethylenically unsad. mono- and dicarboxylic acids and a hydroxylated polycondensate. SOLUTION: An ester E having a low residual acid content is produced from α,β-monoethylenically unsatd. 3-6C mono- and dicarboxylic acids S and a hydroxylated polycondensate P by reacting the acids S with the polycondensate P or a monomer component and/or an oligomer component and/or a polymer component for producing the polycondensate P in the presence or absence of a solvent and/or an esterification catalyst and/or other additives while removing water formed by the reaction and then removing unreacted acids S by distillation. In the step of distillation, water is added to distillate the acids S.

Abstract: PROBLEM TO BE SOLVED: To provide a mixture of acrylic compounds or methacrylic compounds comprising 40-95 wt.% of epoxide (meth)acrylate based on the acrylic compounds or the methacrylic compounds. SOLUTION: A mixture is obtained by a method comprising the following steps: (a) esterifying a hydroxy compound using acrylic acid or methacrylic acid; (b) if necessary, adding additional acrylic acid or methacrylic acid; and (c) subsequently, reacting an excess amount of acrylic acid or methacrylic acid with epoxides in the presence of the esterified product obtained in the step (a).

Abstract: A mixture (I) of acrylic or methacrylic compounds contains 40-95 wt.% epoxy (meth)acrylate and is prepared by: (a) esterification of hydroxyl compounds with acrylic acid or methacrylic acid; (b) optionally addition of further acrylic acid or methacrylic acid and (c) reaction of the excess acrylic or methacrylic acid with epoxide in the presence of the ester product from (a). Independent claims are included for: (i) a radiation curable composition (II) containing (I); and (ii) a process for the curing of (II) by subjecting (II) to energy intensive light or electron beams.
