[0002] 2-vinyloxyethoxyethyl acrylate (VEEA) is a bifunctional special UV acrylate containing ether bonds and ester bonds in its structure. It has low viscosity and good compatibility with polymers. At the same time, due to its two functionalities, it has the characteristics of rapid reaction and curing. It is widely used in coatings, inks and adhesives. At present, the method for preparing 2-vinyloxyethoxyethyl acrylate on the market is usually to use methyl acrylate and diethylene glycol vinyl ether for ester exchange reaction, and use cyclohexane solvent to azeotropically remove methanol to make the reaction proceed in the forward direction.
