| Abstract: | Hydroxymethylation was taken place between melamine and formaldehyde in hydrochloric acid aqueous solu- tion, and products were characterized and tested. Melamine - formaldehyde resin used for over.spray paints floceulant as the reactant concentration,reaction time.temperature and the stability of melamine -formaldehyde resin solution were studied. And the best synthetic conditions were found, melamine/formaldehyde/hydrochloric acid （mole ratio ） = 1 ： 2： 1, reaction temperature 60 ℃ ,reaction time 3 h. |
