| Abstract: | A novel water-solubility the second generation of hyperbranched poly(amido-ester)(1) was synthesized by melt polycondensation of dimethylolpropionic acid as AB2 monomer and 4 as central core which was prepared by acylation reaction of pyromellitic dianhydride and diethanol amine.The structures were characterized by IR,GPC,chemical titration and viscosity measurement.Mn,Mw and Mw/Mn of 4 were 1 683,1 911 and 1.14,and these of 1 were 3 750,4 904 and 1.31,respectively. of 4 and 1 were 0.067 6 dL·g-1 and 0.086 1 dL·g-1,respectively. |
