Abstract (en)

[origin: WO2009018939A1] The present invention relates to a process for heterogeneously catalyzed partial esterification of (meth)acrylic acid with oxyalkylated polyols, wherein the oxyalkylated polyols have at least 3 free hydroxyl groups, and wherein the catalyst is selected from the group comprising acidic ion exchange resins and/or acidic zeolites. The invention further relates to (meth)acrylic esters and urethane acrylates, obtained by a process according to the present invention, and to the use thereof as radiation-curable compounds.
