実験手順

An amount 98.2 g of melamine, 100.6 g of isocyanuric acid (molar ratio 1:1) and 28.5 g of a polycarbonate were charged into a four-necked flask equipped with a condenser and a stirrer, further a solvent mixture comprising 2000 g of tetrahydrofuran and 222 g of water was added and then heating was initiated under stirring. After the temperature in the system reached 62° C. in about one hour, the mixture was aged at the same temperature for one hour and 20 minutes to complete the reaction. Subsequently, the solvent was filtered off, and the product was dried under reduced pressure at 50° C. for 5 hours, followed by pulverization to give a melamine-cyanuric acid adduct subjected to surface treatment.
