POLYMERIZATION AND APPLICATION OF 2-METHACRYLOYLOXYETHYL PHENYL PHOSPHATE IN COATINGS

2-Methacryloyloxyethyl phenyl phosphate (MEPP) was synthesized by reac ting 2-hydroxyethyl methacrylate (2-HEMA) with phenyl dichlorophosphat e (PDCP) followed by hydrolysis. This acrylic monomer containing the p hosphate group was introduced into a typical UV-curable acrylated epox y system as an adhesion promoter. Good adhesion properties and solvent resistance of the films after UV curing were obtained in the presence of MEPP, although there was a decrease in the curing rate. When MEPP was introduced into acrylated epoxy resin, the contact angle remarkabl y decreased indicating that the wetting ability was improved. When MEP P was applied to the synthesis of the water-soluble acrylic resins cur ed with various water-soluble epoxy resins at 25-degrees-C, the adhesi on and corrosion resistance of coating films was improved.
