| Abstract: | Four polyimides were synthesized via copolymerization of pyromellitic dianhydride(PMDA),4,4'-diaminodiphenyl(ODA) and 1,3-bis(4-aminophenoxy)benzene(TPER) at different monomer ratios.Their properties were characterized by Ubbelohde viscometer,XRD,SEM and TGA.The results showed that the introduction of TPER caused the change of PI films from amorphous to semicrystalline,and also the toughness of PI films was improved by the flexibel chain in the TPER molecules.When the TPER content was low,due to the coopera... |
