Emulsification of the epoxy resins, onto which hydrophilic groups were introduced by simultaneous co-graft polymerization with electron beam irradiation, were studied. Resins modified with use of ionic monomers such as methacrylic acid (MAc), diethylaminoethyl methacrylate (DE), tetramethylammonium methacrylate (TMAMA), or methacryloyloxyethyltrimethyl ammonium chloride (QDM) formed latexes, when they were dissolved into small amounts of solvents followed by the addition of water. A higher composition of hydrophilic monomer in the resin-monomer mixture gave a latex with a smaller particle size and higher storage stability. TMAMA and QDM, both of which were incompatible with epoxy resin, were very effective in decreasing the particle size and increasing stability of a latex. It was also ascertained that an alkyd resin were able to emulsified similarly by grafting of 2-hydroxyethyl methacrylate and MAc.
