摘要：
A series of new segmented poly(siloxane-imide)s having ester internal functions were synthesized by the direct polycondensation in solution (DMF) of N,N-bis(hydroxyethyl)benzophenonetetracarboxylic diimide (I), with siloxane diacids. So, avoiding the use of the acid chloride as intermediates, the copolymers were obtained with good yields but with low molecular weights. The characterization (by IR and H-1 NMR spectrometry and GPC) and a comparative study on the properties (solubility, thermal behaviour, morphology) of the monomers and obtained copolymers are also presented.
