Due to excellent performenees, photosensitive polyimides (PSPIs) was gainded extensive applications in many new technology fields and became the research hotspot. Photosensitive polyimide (PSPD was synthesized from pyro-mellitic dianhydride (PMDA), 4,4'-diaminodiphenyl ether (ODA), which selectting maleic anhydride(MA) as photosensi-tive group. It was find that the properties of PSPI which end-capped with MA was better and photosensitive group was in-troduced successfully. The structure and properties was characterized by the means of Fourier transform infrared spectros-copy (FTIR) and thermogravimetric analysis (TGA).
