About 0.25 mol of fine granular hydrated silica 0.5 mol of fine granular magnesium silicate, 0.5 mol of phenol, 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 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 and magnesium chloride. About 1 mol of ethylene chloride is added to the resinous product 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 an organic silicon acid resinous product. The granular resinous product is then washed with water and filtered to remove the magnesium chloride.
