Conditions

Temperature
80 °C

Procedure

10 g of melamine and 2.5 g of tetramethylmelamine are added to 80 ml of water and heated to 80° C. Thereafter, 6 g of formaldehyde are added as formalin solution and kept at 70° C. for 15 min. Cooling and evaporation down on a rotary evaporator are then effected. The resin is obtained as a white solid. The resin melts at 120° C.-125° C. The molar mass is about 350.
