Title:
CHALCOGEN-BASED DIAMINE, POLYAMIC ACID AND POLYIMIDE PRODUCED THEREFROM, AND POLYIMIDE FILM COMPRISING POLYIMIDE
Document Type and Number:
WIPO Patent Application WO/2020/071782
Kind Code:
A1
Abstract:
The present invention provides a polyamic acid which is a product of a polymerization reaction of a chalcogen-based diamine represented by chemical formula 1 and an acid dianhydride, a polyimide obtained therefrom, a polyimide film, and a chalcogen-based diamine. [Chemical formula 1] In chemical formula 1, X1 is selenium dioxide (SeO2), tellurium (Te), tellurium dioxide (TeO2), or a combination thereof, and Ar1 and Ar2 are each independently selected from the group consisting of chemical formula 1-1 to chemical formula 1-3. [Chemical formula 1-1] [Chemical formula 1-2] [Chemical formula 1-3] In chemical formulas 1-1 to 1-3, * represents a binding site, and R1 to R4 are each independently selected from the group consisting of hydrogen, fluorine, C1-C30 alkyl groups, and C1-C30 perfluoroalkyl groups.
