실험 절차
About 10 parts by weight of the diurea silicate as produced in Example 5 are mixed with 10 parts by weight of a 37% aqueous solution of formaldehyde containing sufficient sulfuric acid to produce a pH of 4 to 6 when mixed. The mixture is rapidly and thoroughly mixed, and the reaction is exothermic. In a short period of time, a white solid poly(formaldehyde urea silicate) resinous product is produced.
