摘　　要：采用对苯二胺和丙烯酸甲酯为原料经迈克尔加成反应合成了多官能团化合物N,N,N',N'-四丙酸甲酯-1,4-苯二胺.以该化合物和乙二胺为单体,通过熔融聚合-溶液聚合联用的方法,制备了耐热性好、水溶性高的芳香族超支化聚酰胺胺材料.利用傅立叶变换红外光谱和核磁共振氢谱对所合成的产物进行结构表征.以布洛芬为客体小分子,研究了芳香族超支化聚酰胺胺化合物对其在水中的增溶效果.结果表明,布洛芬的溶解度随超支化聚合物浓度增加而增加,2 mg/m L聚合物可提升布洛芬溶解度20倍.A multifunctional compound N,N,N’,N’- tetramethyl propionate- 1,4- phenylenediamine was synthesized through Michael addition reaction using p- phenylenediamine and methyl acrylate as the starting materials. Then the aromatic hyperbranched poly（amidoamine） with good heat resistance and water solubility wasprepared using the multifunctional compound and ethylenediamine as monomers by a melt polymerization-solution polymerization combination technique and it was characterized by fourier transform infrared spectroscopy and nuclear magnetic resonance hydrogen spectrum. The enhancement capability of aqueous solubility was also investigated using ibuprofen as the guest molecule. The results show that the solubility of ibuprofen increases with the increasing concentration of the hyperbranched polymer, and it increases by 20 times with 2 mg/mL polymer material.
