Procedure
Formaldehyde reacts with melamine to form methylol melamine: ##STR2## Polymerization of melamine and formaldehyde is inhibited by keeping the solution at an alkaline pH, by keeping the temperature and concentration of reactants somewhat low, and by the inclusion of methanol in the formalin solution (formalin solutions typically include about 15% methanol to inhibit polymerization of formaldehyde molecules).
