An aromatic polyester amide copolymer, the aromatic polyester amide copolymer and a prepreg employing a prepreg laminated body, and the metal foil-clad laminate and printed wiring board employing the prepreg or prepreg laminate

摘要

An aromatic polyester amide copolymer, a prepreg, a prepreg laminate, a metal foil-clad laminate and printed wiring board is disclosed. The repeating unit (A) 20 ~ 40 mole% derived from the disclosed aromatic polyester amide copolymer is an aromatic diol; At least one repeat unit of 20 to 40 mol% of the repeating unit (B ') derived from the repeating unit (B) derived from an aromatic amine and aromatic diamine having a phenolic hydroxyl group; And aromatic dicarboxylic repeat units derived from the dicarboxylic acid (C) containing 20 to 60 mol% and the repeating units (A) derived from the aromatic diol includes a repeating unit (RCN) derived from resorcinol It characterized.
