AbstractA novel AB(2)-type monomer diethyl 5-(4-hydroxyethoxyphenylazo)isophthalate for preparing hyperbranched azo polymers (HBPAZO) was synthesized. The monomer obtained was characterized by IR spectra, UV-Vis spectra, H-1 NMR spectrum and C NMR spectrum. The TG-DTG/DTA curves show that the decomposition of the monomer proceeds in four steps. During the second-step decomposition, the mass loss occurs between 480.5 K and 579.0 K and the phenomena of condensing to HBPAZO for the melted monomer was found. So it is inferred that this temperature range is the best for polycondensation of the melted monomer, which is very important for synthesizing of HBPAZO.
