The flame retardant poly(diallyldimethylammonium) and polyphosphate polyelectrolyte complex and the curing agent m-Phenylenediamine were blended into diglycidyl ether of bisphenol A (DGEBA)-type epoxy resin to prepare flame-retardant epoxy resin thermosets. The effects of poly(diallyldimethylammonium) and polyphosphate on fire retardancy and thermal degradation behavior of epoxy resins (EP)/poly(diallyldimethylammonium) and polyphosphate composites were tested by Limiting Oxygen Index, UL-94, cone calorimeter tests, and thermogravimetric analysis and compared with pure EP. The results showed that the Limiting Oxygen Index value of EP/poly(diallyldimethylammonium) and polyphosphate composite could reach 31.9%, and UL-94 V-0 rating at 10 wt% poly(diallyldimethylammonium) and polyphosphate loading. Meanwhile the cone calorimetry peak heat release rate and total heat release were reduced up to 55.2% and 21.8%, respectively; smoke production rate and total smoke production were also declined significantly, compared with those of pure epoxy resins. Poly(diallyldimethylammonium) and polyphosphate played a very good flame-retardant effect on epoxy resins.

聚（二烯丙基二甲基铵）和聚磷酸盐聚电解质复合物作为成炭环氧树脂的阻燃剂

将阻燃聚(二烯丙基二甲基铵)聚磷酸盐聚电解质络合物和固化剂间苯二胺共混到双酚A(DGEBA)型环氧树脂的二缩水甘油醚中制备阻燃环氧树脂热固性树脂。通过限氧指数、UL-94、锥形量热仪测试和热重分析测试聚（二烯丙基二甲基铵）和聚磷酸盐对环氧树脂（EP）/聚（二烯丙基二甲基铵）和聚磷酸盐复合材料的阻燃和热降解行为的影响并进行比较用纯EP。结果表明，EP/聚（二烯丙基二甲基铵）和聚磷酸盐复合材料的限氧指数值可达31.9%，在10wt%聚（二烯丙基二甲基铵）和聚磷酸盐负载量下的UL-94 V-0等级。同时锥形量热法峰值放热率和总放热率分别降低了55.2%和21.8%；与纯环氧树脂相比，产烟率和总产烟量也有明显下降。聚（二烯丙基二甲基铵）和聚磷酸盐对环氧树脂起到了很好的阻燃作用。
