Abstract: |
An efficient process for synthesizing the ultrabranched polyester-amine includes aminolysis of acid anhydride, acetylizing hydroxy to obtain nanometer N-(2-acetoxyethyl)-N-(1,3'-dicarboxy benzoyl) amine, putting it along with catalyst in reaction tube, heating reaction in N2 atmosphere, vacuumizing, and cooling. Its advantages are simple process and high yield. |
