中文摘要：
基于不同摩尔比哌啶和三羟甲基丙烷三丙烯酸酯（TMPTA）的反应，合成了系列两亲性超支化聚（酯-胺），设计哌啶与TMPTA摩尔比为1：1、1：2和1：3的模型反应，通过分析模型反应产物的氢核磁谱图，确定了化学位移为4．0～4．2间各峰的归属．进而可用来计算聚合物中各种特征结构单元的相对含量及支化度。采用动态光散射和透射电镜技术分析该聚合物在丙酮／酸性水溶液中的聚集行为，研究了聚合物结构和溶液条件对聚集体尺寸的影响。
英文摘要：
A series of hyperbranched poly （easter-amine）s （HPEA） were synthesized by Michael addition reaction between trimethylolpropanetriacrylate （TMPTA） and piperazine at various molar ratios. Based on analysis of the 1^H-NMR spectra of model reaction products derived from TMPTA and piperidine at molar ratio of 1 ： 1, 1 ： 2 and 1 ： 3, the characteristic peaks within 4.0-4.2 were used to distinguish the characteristic structural units in HPEA. The aggregation behaviors of HPEA in acetone-acidic water selective solvent were studied by dynamic light scattering and TEM techniques. The influence of polymer structure and the solution conditions on the size of the aggregates were investigated.
