反応手順

The alkylidenediamine (ADA for abbreviation) is added into a round-bottom flask equipped with a stirring, a reflux condenser and a thermometer, and cooled to 10° C. below under nitrogen. The methanol solution of pentaerythritol tetraacrylate (PETA for abbreviation) is then added to the flask, and the mixture is allowed to react at 25˜35° C. for 20˜48 hours, preferably, at 25˜30° C. for 24˜30 hours. The result solution is subjected to vacuum distillation to remove excess alkylidenediamine (ADA) and methanol at 60˜110° C. for 5˜10 hours, to obtain a light-amber viscous material, i.e., intermediate pentaerythritol core, amino terminated dendrimer (PETA-ADA-12NH for abbreviation), wherein a general reaction equation thereof is as follows:
