| Abstract: | 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. |

| Keywords: | Hyperbranched polyamide Self-condensation reaction End-capping reaction In-situ modification |
