TRANSESTERIFICATION REACTION OF ALKOXYLATED BISPHENOL-A AND METHYL METHACRYLATE

摘要

The present invention relates to a new method of making the dimethacrylate ester of alkoxylated bisphenol-A via transesterification with methyl methacrylate. This transesterification reaction proceeds at low temperatures and is driven by the removal of methanol as a methanol/saturated hydrocarbon azeotrope. The lower temperature reaction advantageously inhibits polymerization of the feed ester. The reaction is catalyzed by potassium based catalysts.
