A series of polyetherimides were synthesized by polycondensation reaction at high temperature of 2, 2-bis [4, 4–(3, 4–dicarboxyphenoxy) phenyl] propane dianhydride with various aromatic diamines. These polymers are easy soluble in polar aprotic solvents such as N-methylpyrrolidinone, dimethylformamide or dimethylacetamide or even in less polar liquids such as chloroform. They show high thermal stability, with decomposition ...
