Hyperbranched poly(amido amine) (h‐PAMAM) was synthesized from different feed ratios of diethylene triamine and methyl acrylate by the simple one‐pot and commercial synthesis method. Reaction procedures and products were intensively studied by FTIR, inherent viscosity and fluorescence techniques. The ill‐structured h‐PAMAM shared similar chemical and physical properties with well defined poly(amido amine) (PAMAM) dendrimers in generation 2 or 3. Its strong fluorescence properties were influenced by pH values, solvents, concentrations, terminal groups and other factors.
