About 1 mol of fine granular hydrated silica, 0.5 mol of cresol and 1 mol of silicon tetrachloride are slowly added simultaneously while agitating and keeping the temperature below the boiling temperature 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 1 mol of a ketone, acetone, is 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 granules of organic silicon acid resinous product.
