Procedure

Separately, 6 parts of melamine, 11 parts of 37 weight % aqueous solution of formaldehyde and 30 parts of water were heated to 60° C. while stirring. After 30 minutes, a clear aqueous solution of a mixture (precondensate) of melamine, formaldehyde and a melamine-formaldehyde precondensate was obtained. The aqueous solution had a pH of 6 to 8.
