WHOLLY AROMATIC POLYESTER AMIDE COPOLYMER RESIN, POLYMER FILM INCLUDING THE WHOLLY AROMATIC POLYESTER AMIDE COPOLYMER RESIN, FLEXIBLE METAL-CLAD LAMINATE INCLUDING THE POLYMER FILM, AND FLEXIBLE PRINTED CIRCUIT BOARD INCLUDING THE FLEXIBLE METAL-CLAD LAMINATE

摘要

Disclosed are a wholly aromatic polyester amide copolymer resin, a polymer film including said wholly aromatic polyester amide copolymer resin, a flexible metal-clad laminate including said polymer film, and a flexible printed circuit board including said flexible metal-clad laminate. The wholly aromatic polyester amide copolymer resin comprises: 5-25 moles of a repeating unit (A) derived from an aromatic hydroxy carboxylic acid; 20-40 moles of at least one repeating unit selected from the group consisting of a repeating unit (B) derived from an aromatic amine having a phenolic hydroxy group and a repeating unit (B') derived from an aromatic diamine; 20-40 moles of a repeating unit (C) derived from an aromatic dicarboxylic acid; 5-20 moles of a repeating unit (D) derived from an aromatic diol; and 5-20 moles of a repeating unit (E) derived from an aromatic amino carboxylic acid.
