Abstract:
Provided is a liquid crystal polyester amide resin which has a good hue. Specific monomers are polymerized using a specific catalyst. The specific monomers are composed of: at least one kind of a monomer selected from among aromatic aminocarboxylic acids, aromatic hydroxyamines and aromatic diamines; and at least one kind of a monomer selected from among aromatic hydroxy carboxylic acids, aromatic dicarboxylic acids or aliphatic dicarboxylic acids, and aromatic diols or aliphatic diols. It is preferable that the content of the at least one kind of a monomer selected from among aromatic aminocarboxylic acids, aromatic hydroxyamines and aromatic diamines is from 0.1 mol % to 85 mol % (inclusive).
