摘　　要：以2-羧乙基苯基次膦酸(CEPPA)和己二胺(HMDA)为原料,通过胺化反应,制备了化合物CEPPAHMDA。应用FTIR、1 H-NMR、EDS、TGA分别表征了CEPPA-HMDA的化学结构、元素组成和热稳定性,并将CEPPA-HMDA加入到尼龙6的反应体系中,制备了共聚型阻燃尼龙6。结果表明:HMDA一端氨基可以与CEPPA上的羧基反应,当n(CEPPA)∶n(HMDA)=1∶1.1,反应温度为70℃,反应时间为5h时,CEPPA-HMDA的收率可达96.27%;其中HMDA一端的氨基与CEPPA上的羧基反应;CEPPA-HMDA的初始分解温度达到270℃,能够满足与尼龙6共聚所需的反应条件;当CEPPA-HMDA添加量质量分数为9%时,共聚型阻燃尼龙6的LOI值达到27.0。CEPPA-HMDA was prepared through amination by taking 2-carboxyethyl phenyl phosphinic acid（CEPPA）and Hexanediamine（HMDA）as raw materials,and its chemical structure,elemental composition,heat stability were characterized by FTIR,1 H-NMR,EDS, TGA respectively. Copolymerizable flame retardant nylon 6was prepared through adding CEPPA-HMDA in nylon 6.The results show that one-end amino of HMDA can react with the carboxyl in CEPPA and the optimum reaction conditions are as follows：n（CEPPA）∶n（HMDA）=1∶1.1;reaction temperature 70℃;reaction time 5h.Under such conditions,the yield of CEPPA-HMDA can reach 96.27%.Furthermore,one-end amino of HMDA reacted with carboxyl in CEPPA.When the initial decomposition temperature of CEPPA-HMDA reaches270℃,reaction condition with nylon 6can be met.When mass fraction of CEPPA-HMDA is 9%,LOI value of copolymerizable flame retardant nylon 6reaches 27.0.
