摘要

A novel AB3-type monomer was prepared from gallic acid and DL-2-aminobutyric acid

and used for the synthesis of the biocompatible hyperbranched poly(ester-amide)s by self-polycondensation. The polymers were characterized via FTIR and NMR spectroscopy and thermal analysis

and the average degree of branching of the polymers was estimated to be 0.75.The polymers with abundant acetyl end groups were found to be amorphous with lower intrinsic viscosity

better thermalstability and excellent solubility.
