Poly- adipic -anhydride （PAA） and chlorine siloxane （Si3 and Si5 ） get together for the synthesis of adipic acid anhydride monomer silicon ester. Suffcient pressure and at room temperature under dry conditions, poly adipic anhydride prepolymer dissolved in toluene or benzene, and warm until the solid dissolved completely, dropping a certain molar mass of the Si3 and Sis, reflux temperature, the reaction must time to get together silicon - based esters of adipic acid anhydride. Vacuum steamed in addition to most of the solvent, under vacuum at room temperature to fully dry. The samples with IH - NMR, DSC, TGA, and intrinsic viscosity measurement was carried out by means of characterization. Examined the reaction solvent, reaction time, reaction temperature and other factors. Obtained by analyzing multiple samples 1H -NMR, DSC -TGA, the results show that the ideal response. Measured multiple samples of the intrinsic viscosity values, indicating that the polymer product obtained has the typical characteristics.
