POLYIMIDE PRECURSOR COMPOSITION COMPRISING CROSSLINKABLE DIANHYDRIDE-BASED COMPOUND AND ANTIOXIDANT, AND POLYIMIDE FILM PREPARED THEREFROM

摘要

The present invention provides a polyimide precursor composition comprising: a polyamic acid solution prepared by polymerizing one or more types of dianhydride monomers and one or more types of diamine monomers in an organic solvent; and an antioxidant having a 5 wt% weight loss temperature of 380℃ or higher, wherein the dianhydride monomer comprises a crosslinkable dianhydride-based compound and the crosslinkable dianhydride-based compound comprises at least one triple bond in the molecular structure.
