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.
- N-(diaminobenzoyl)glycine,
- hyperbranched polyamide,
- self-polycondensation,
- end-capping reaction
