| Abstract: | A series of copolymerized polyimide films were prepared from pyromellitic dianhydride,2,2′-bis[3-phenyl-4-(4-aminophenoxy)phenyl]propane(BPAPOPP)and 4,4′-diaminodiphenyl ether via twostep copolycondensation.The chemical structure of the films was characterized by infrared spectroscope and differential scanning calorimeter.The properties of the films were characterized by thermal mechanical analyzer.The results show that the glass transition temperature of polyimide films prepared is low.The thermal properties of the films decrease with increase of BPAPOPP content,while whose solubility is improved. |
