摘要：
New dicarboxybisimide monomers have been synthesized. Polyimidophosphoanhydrides are prepared by reacting dicarboxybisimides with dichlorophenylphosphine oxide by the two phase polycondensation in dichloromethane-aq alkaline solution using a phase transfer catalyst and characterized by melting point, elemental analysis, viscosity measurement, molecular weight determination, ESCA study, IR, PMR and P-31-NMR spectral data and X-ray diffraction studies. The thermal properties and flame retardancy of the polymers have been evaluated.
