(57) [Summary] [Objective] To provide a novel epoxy composition suitable for drilling fluids, adhesives, coatings and the like. (A) heating in a reaction zone a reaction mixture of a catalyst having a polyol having at least three hydroxyl groups in which at least two hydroxyl groups are vicinal, (B) mixing the epoxy resin with the reaction mixture in an amount sufficient to provide 15-75 wt% epoxy in the epoxy polyether polyol, and (c) continuing condensation and copolymerization to remove water. Then, an epoxy polyether polyol is produced. |
