A process for producing an epoxy silane oligomer consists of: reacting (i) glycidoxy silane having 2 alkoxy groups with water in a molar ratio of 0.4 to 1.0 water to silane monomer (i) in the presence of a catalyst selected from the group consisting of an ion exchange resin, a titanate, a Lewis acid, a zirconate, an alkylammonium salt, or a quaternary ammonium organofunctional silane reacted with at least one of ceramic, silica gel, precipitated silica, fumed silica, alumina or aluminosilicate support, wherein said water is continuously fed during the reaction, and the by-product is continuously removed during the reaction. |
