About 0.5 mol of fine granular hydrated silica, 0.5 mol of resorcinol and 1 mol of silicon tetrachloride are slowly added while agitating and keeping the temperature below the boiling temperature of the mixture for 1 to 2 hours; the reaction is complete in 2 to 8 hours, thereby producing a phenol chlorosilicon acid resinous product. To this resinous product about 0.5 mol of phenol is added while agitating for 1 to 2 hours, thereby producing an organic silicon acid resinous product. Hydrogen chloride evolves from the mixture.
