The results of FT-IR 1H-NMR indicate the structure of polyester, and the 13C-NMR analysis of three quaternary carbon showed the existing of hyperbranched struscture, MALDI-TOF MS showed the hyperbranched polyester structure, the degree of branching of the polyesters determined by 13C-NMR being 0.408. The esterification reaction kinetics followed a second-order equation and the reaction rate was controled by the concemtration of carboxyl group and hydroxyl group,-d/dt=K.

以IR、1H-NMR证实了聚酯结构的存在，13C-NMR谱图上3种季碳的特征峰有力证实了超支化分子结构的存在，MALDI-TOF MS证明了超支化聚酯的成功合成，并计算超支化聚酯的支化度为0.408；探讨并建立了超支化聚酯的缩聚反应动力学方程－d/dt=K，该缩聚反应属于二级反应，反应速率由羟基浓度和羟基浓度共同决定。
