摘　　要：以三聚氰胺、六氯环三磷腈和氨为原料,通过三聚氰胺和六氯环三磷腈缩合,再氨化,最后缩聚制得了三聚氰胺改性聚氨基环三磷腈。三聚氰胺与六氯环三磷腈缩合的较佳条件:反应温度为80℃,反应时间为18h;缩聚的较佳条件:聚合温度为180℃,聚合时间为15min;通过三聚氰胺改性,明显提高了产品的磷收率,降低了产品的吸湿性和水溶性,改善了产品的热稳定性。Polyaminocyclotriphosphazene modified with melamine was synthesized by the condensation of hexachlorocyclotriphosphazene（TCP）and melamine（MA）,then ammoniation with ammonia,final polycondensation.The results showed that the optimum conditions of condensation were as follows：reaction temperature being 80 ℃,reaction time being 18 h.The optimum conditions of polycondensation were as follows：reaction temperature being 180℃,reaction time being 15 min.The recovery and thermal stability of the product were improved significantly,and the moisture absorption and water-solubility were reduced by melamine modification.
