超支化聚酰胺的合成与表征
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、1H NMR、DSC和TGA对超支化聚合物进行了表征。

Synthesis and Characterization of Hyperbranched Polymers
Abstract:
A novel AB2 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.
