반응 단계
The said melamine silicate as produced in Example VII is added to about 2 mols of formaldehyde in an aqueous solution and dilute sulfuric acid is added until the pH is 4 to 5.5, then heated to 70° to 100° , while agitating, for 15 to 60 minutes, thereby producing a white, solid resin, poly (formaldehyde melamine silicate). The said resin is not soluble in acetic acid and is resistent to strong acids and alkalis. On heating, the said resin softens very little and is destroyed before it will melt.
