METHOD FOR PREPARING MT RESIN

WIPO Patent Application WO/2015/143592

A1

Provided is a method for preparing an MT resin, comprising the following steps: a first step: adding anhydrous toluene, anhydrous ethanol and an alkoxyl silane into a reaction vessel, and then adding acetic acid dropwise into the reaction vessel under the conditions of 50 - 70°C and the protection of nitrogen so as to react the alkoxyl silane with the acetic acid, with a fluorine-contained methylsulphonic acid or fluorine-contained methylsulphonic acid salt as a catalyst, wherein the molar ratio between the alkoxyl silane and the acetic acid is 1 : 0.95 - 1.2; a second step: removing the solvents in the reaction vessel; and a third step: under the conditions of 80 - 100°C, adding tetramethyldihydrodisiloxane into the reaction vessel, and then further adding acetic acid dropwise into the reaction vessel and fully reacting to obtain the MT resin, wherein the molar ratio between the tetramethyldihydrodisiloxane and the alkoxyl silane is 1 : 0.45 - 0.55, and the molar ratio between the acetic acid and the alkoxyl silane is 1 : 0.9 - 1.2. The method for preparing the MT resin of the present invention is simple, and the MT resin prepared therefrom has a stable structure.
