摘要
由 3,5 二硝基苯甲酰氯和氨基乙酸合成了AB2 型单体N (3,5 二氨基苯甲酰 )氨基乙酸。利用此单体在极性非质子溶剂NMP中的自缩聚反应 ,合成了新型超支化聚酰胺 ;将其与乙酸酐或酰氯反应 ,得到 5种封端的超支化聚合物。用FTIR、1HNMR。
A novel AB 2 type monomer, N-(3,5-diaminobenzoyl)glycine was synthesized in two-steps. A hyperbranched polyamide(2a) was prepared from this new monomer by self-polycondensation, and five hyperbranched polymers(2b~2f) with various end-groups were prepared by end-capping reactions of 2a with acetic anhydride or acid chlorides. The six polymers were characterized by FTIR, 1H NMR, DSC and TGA.
