WHOLLY AROMATIC POLYESTER AMIDE COPOLYMER RESIN, FILM CONTAINING RESIN, FLEXIBLE METAL FOIL LAMINATE CONTAINING FILM, AND FLEXIBLE PRINTED CIRCUIT BOARD EMPLOYING FLEXIBLE METAL FOIL LAMINATE

摘要

Disclosed are a wholly aromatic polyester amide copolymer resin, a polymer film containing the wholly aromatic polyester amide copolymer resin, a flexible metal foil laminate containing the polymer film, and a flexible printed circuit board employing the flexible metal foil laminate. The disclosed wholly aromatic polyester amide copolymer resin comprises: 5-25 parts by mole of a repeating unit (A) derived from an aromatic hydroxy carboxylic acid; 37.5-47.5 parts by mole of at least one repeating unit selected from the group consisting of a repeating unit (B) derived from an aromatic amine having a phenolic hydroxyl group and a repeating unit (B') derived from diamine; and 37.5-47.5 parts by mole of a repeating unit (C) derived from an aromatic dicarboxylic acid.
