Reaction Steps
The cresol silicoformate produced in Example XV is added to 60 parts by weight of an aqueous solution containing about 37% formaldehyde, then dilute sulfuric acid is added until the pH is 5 to 6. The mixture is heated to 60° to 90° C. for about 20 to 50 minutes while agitating at ambient pressure, thereby producing light brown poly(formaldehyde cresol silicoformate) resin.
