摘要
以苯酚、六氯环三磷腈(TCP)和氨为原料,通过苯酚和TCP缩合,再氨化,最后缩聚制得了苯氧基改性聚氨基环三磷腈。结果表明:TCP与苯酚缩合的较佳条件与两者的量的比有关:当n(TCP)∶n(苯酚)∶n(KOH)=1∶1.1∶1.3时,缩合温度为85℃,缩合时间为5h;当n(TCP)∶n(苯酚)∶n(KOH)=1∶2.2∶2.6时,缩合温度为95℃,缩合时间为7h。缩聚的较佳条件是:聚合温度为180℃,聚合时间为15min。通过苯氧基改性,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 phenoxy was synthesized by the condensation of hexachlorocyclotriphosphazene(TCP)and phenol,then ammoniation with ammonia,final polycondensation.The results showed that the optimum conditions of the condensation were associated with the molar ratio of TCP and phenol:When n(TCP)∶n(phenol)∶n(KOH)=1∶1.1∶1.3,reaction temperature being 85 ℃,reaction time being 5 h,but when n(TCP)∶n(phenol)∶n(KOH)=1∶2.2∶2.6,reaction temperature being 85℃,reaction time being 5 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 significantly improved,and the moisture absorption and water-solubility were reduced by phenoxy modification.
