| description | Process for hydrolyzing an epoxy resin by reacting said epoxy resin with water in the presence of a catalyst. This invention is characterized by conducting the reaction in the absence of a polyhydric phenol and substantial quantities of an organic solvent and in the presence of a catalytic of a catalyst comprising (1) at least one dicarboxylic acid and (2) at least one phosphonium compound wherein the molar ratio of (1) to (2) is from 1:1 to 20:1. Hydrolyzed epoxy resins produced by the process of this invention are useful in coating compositions.
Procédé d'hydrolyse d'une résine époxyde en faisant réagir ladite résine époxyde avec de l'eau en présence d'un catalyseur. La caractéristique de cette invention est d'effectuer la réaction en l'absence d'un phénol polyhydrique et de quantités substantielles d'un solvant organique, et en présence d'une quantité catalytique d'un catalyseur comprenant (1) au moins un acide dicarboxylique et (2) au moins un composé de phosphonium, où le rapport molaire entre (1) et (2) va de 1/1 à 20/1. Les résines époxydes hydrolysées produites selon le procédé de cette invention sont utilisées dans des compositions de revêtement. |
