A new segmented polysiloxaneimide was synthesized by solution polycondensation of N, N bis(hydroxyethyl)benzophenontetracarboxylic diimide with siloxane diacid chloride. The copolymer was obtained with good yield and high molecular weight. The characterization by IR and 1H-NMR spectrometry and a study of the properties such as solubility and thermal behaviour of this copolymer are presented. A corona poling study was performed to obtain information about the piezoelectric behaviour of polysiloxaneimide. The remanent dielectric constants of the polarized samples were compared with those of well-known piezoelectric polymers.
