摘要： PROBLEM TO BE SOLVED: To produce an epoxy resin having excellent curability by using a mixture of dihydroxybenzophenone with other polyhydric phenol as polyhydric phenols. SOLUTION: To a mixture prepared by mixing 4,4'-dihydroxy-benzophenone with a polyhydric phenol (e.g. bisphenol A) in a ratio in the range of (30-90)/(70-10) by weight, about 2-20 equivalents, per equivalent of the hydroxyl groups of the polyhydric phenol, of an epihalohydrin (e.g. epichlorohydrin) is added. Next, 0.8-1.2 equivalents of a sodium hydroxide solution is added dropwise to the mixture within about 1-10hr under agitation at about 20-100 deg.C and reacted. After the reaction, the water phase is separated and removed, an unreacted matter is removed by distillation, and the crude resin is withdrawn and dissolved in an organic solvent, an aqueous sodium hydroxide solution is added to the solution to reduce the content of hydrolyzable chlorine atoms, dehydrated, filtered and the solvent is removed to obtain an epoxy resin having low melt viscosity. This epoxy resin is mixed with a curing agent (e.g. diethyltriamine) and 85-95wt.% inorganic filler to obtain a semiconductor sealing material.
