Abstract： With the rapid development of flexible photoelectric technology, the preparation of polyimides with excellent comprehensive properties has become a research hotspot. A series of poly(ester imide)s were prepared by polycondensation of bis(trimellitic acid anhydride) phenyl ester (TAHQ) and three 4,4′-diaminodiphenylmethaners with different substituent groups, and their thermal properties, solubility, mechanical properties and optical properties were studied. The results showed that the polyimide films prepared by TAHQ and 2,2′-bis(trifluoromethyl)l-4,4′-diaminodiphenylmethaner had high glass transition temperature and good visible transmittance, which were expected to be applied in the field of flexible optoelectronics.
