AROMATIC POLYESTER AMIDE COPOLYMER, PREPREG OR PREPREG LAMINATES EMPLOYING THE COPOLYMER, AND METAL CLAD LAMINATES AND PRINT WIRING BOARD EMPLOYING THE PREPREG OR THE PREPREG LAMINATES

摘要

PURPOSE: An aromatic polyester amide copolymer and a prepreg are provided to ensure low thermal expansion ratio, low dielectric constant and low dielectric loss.;CONSTITUTION: An aromatic polyester amide copolymer comprises, based on a whole repeating unit, 20~69 mol% repeating unit derived from an aromatic hydroxy carboxylic acid, 5~20 mol% repeating unit derived from an aromatic amino carboxylic acid, 10~20 mol% repeating unit derived from aromatic diols, 1~10 mol% of at least one selected from a repeating unit derived from aromatic amine with a phenolic hydroxy group and a repeating unit derived from aromatic diamine, and 15~30 mol% repeating unit derived from derived from aromatic dicarboxylic acid.;COPYRIGHT KIPO 2011
