Reaction Steps

69.60 g of 1,6-Hexanediamine (HDA) (0.60 mol) was added into a round-bottom flask with a stirring, a reflux condenser and a thermometer, and cooled to 10° C. below under nitrogen. 74.00 g methanol solution of trimethylolpropane triacrylate (TMPTA) (40%, 0.1 mol) was added to the round-bottom flask, and the mixture is allowed to react at 25° C. for 24 hours. The result solution is subjected to vacuum distillation to remove excess 1,6-Hexanediamine (HDA) (0.60 mol) and methanol at 110° C. for 8 hours, to yield 64.46 g of light-amber viscous material, i.e., intermediate trimethylolpropane core, amino terminated dendrimer (TMPTA-HDA-9NH for abbreviation).
