}A soluble copolyimide was synthesized via the conventional two-step thermal or chemical imidization process by using 2,2-bis[4-(4-aminophenoxy)phenyl]propane(BAPP) and 4,4′-diaminodiphenyl ether(ODA) as the diamine monomer,4,4′-oxydiphthalic dianhydride(ODPA) as the dianhydride monomer in dimethylformamide(DMF).The structure of the copolyimide was characterized by FTIR.The FTIR test indicates that the copolyimide exhibits characteristic peaks of polyimides around 1 780 cm-1,1 720 cm-1 and 725… Expand
