摘要：

New segmented poly(anhydride)s containing pre-formed siloxane-imide sequences have been synthesized. The synthetic strategy involves the preparation of alpha,omega-bis(3-aminopropyl)oligodimethylsiloxane having certain molecular weight, their chemical modification by reaction with trimellitic anhydride, and subsequent polycondensation of the obtained diacid macromers in solution. The acetylation method was used for the in situ activation of the diacids. The structures of partial and final products and their degradability were confirmed by IR and H-1 NMR spectroscopy.
