Abstract
An improved process for preparing epoxy acrylate dispersions from the reaction product of an epoxy resin and carboxyl containing polymer in the presence of tertiary amine in which the carboxyl containing polymer is formed, in situ, in the presence of a solvent solution of the epoxy resin and then subjected to the esterification reaction which can be conducted in a single pot.
