Hyperbranched polymer (amine-ester) with terminal alcohol group (HPAE) was synthesized by polycondensation of N,N-diethyol-3-amine-methylpropionate(prepared by Miachael addition reaction of methyl acrylate with diethanolamine) as an A2B-type monomer with trimethylol propane as the core moiety, proceeding in one-step procedure in the melt with p-toluenesulfonic acid as catalyst. Then, it was modified by ferrocenecarboxylic acid to obtain ferrocene-containing hyperbranched poly (amine-ester). The reaction conditions were obtained: reaction time 4h at temperature 140℃,catalyst dosage 2.5% based on the mass of reaction materials, molar feed ratio n(OH):n(ferrocenecarboxylic acid)=1:0.8. The obtained polymer was characterized by means of IR, 1HNMR, it shows that the ferrocene was successfully grafted to the HPAE, and the grafting rate reached 70%.
