Procedure

Moist silicic acid gel, equivalent to 20 parts by weight of dry silicic acid gel, about equal parts by weight of phenol and 3 parts by weight of sodium carbonate are heated to just below the boiling point of phenol for 20 to 60 minutes, thereby producing tan granules of phenol silicate. The phenol silicate is mixed with 20 parts by weight of crotonaldehyde then heated to 70° to 90° C. while agitating under ambient pressure for 20 to 70 minutes, thereby producing a yellow poly(crotonaldehyde phenol silicate) resin. The resin is soluble in acetic acid.
