摘要
以 3 ,5 二硝基苯甲酰氯和对氨基苯甲酸为原料 ,经两步反应合成了新型AB2 型单体 4 ( 3 ,5 二氨基苯甲酰氨基 )苯甲酸。在溶液中通过自缩聚反应合成了新型超支化聚芳酰胺 ,将其活性端氨基与酰氯反应 ,经原位改性合成了五种封端的超支化聚芳酰胺 ,并利用IR、1HNMR、DSC及TG等方法对所合成的六种新型超支化聚合物的结构和性能进行了表征与测试。
A new AB 2 monomer,4-(3,5-diaminobenzamido)benzoic acid,has been prepared from 4-aminobenzoic acid and 3,5-dinitrobenzoyl chloride.Hyperbranched aromatic polyamide was synthesized by self-condensation reaction of 4-(3,5-diaminobenzamido)benzoic acid,and five kinds of end-capped hyperbranched aromatic polyamides also were prepared by end-capping reaction with acid chlorides.The structures and properties of the resulting hyperbranched polyamides were characterized by IR, 1H NMR,DSC,and TGA etc.
