This paper studies synthetic method and thermostability of poly-N-(para-, meta-, ortho-carboxyphenyl)-rosinmaleimide ester. In the presence of catalysts, the yields of three rosinmaleic anhydride polyesterimides (PPEI, PMEI, POEI) formed by N-(para-, meta-, ortho-carboxyphenyl)-rosinmaleimides condensing with glycol are 80%, 80%, 72%respectively. The catalysts, H2SO4 (conc.), H3PO4, H3BO3, ZnO, Sb2O3-(CH3CO2 )2Zn (1:1)have catalysis to condensing reaction. The catalystic effect of H3BO3-ZnO(1:1)is the best,and raising the reactive temperature,the reactive yield is increased. The determination of solubility test,FTIR,1H-NMR spectrum indicates PPEI, PMEI, POEI are the target products. The determining curves of thermal gravimetric(TGA)indicate ONSET temperature of PPEI,PMEI,POEI is above 470, and they have good thermostability.
