Vorschrift

Bisphenol F epoxy resin (Nihon Kayaku Co., Ltd. RE-404P, epoxy equivalent 160 g/eq., amount of hydrolysis 30 ppm) was dissolved in toluene, and added dibutylhydroxy toluene as the polymerization inhibitor therein, then temperature was risen up to 60° C. Thereafter, acrylic acid in 100% equivalent amount to epoxy group was added, further temperature was risen up to 80° C. Then trimethylammonium chloride as the reaction catalyst was added thereto, followed by stirring at 98° C. for about 50 hours. The resultant reaction mixture was washed with water, and toluene was distilled out to obtain epoxy acrylate of bisphenol F (Epoxyacrylate C).
