Abstract: PURPOSE:To obtain a polyamide copolymer being lowly colored, being excellent in mechanical and thermal properties and having low water absorptivity by mixing a specified dicarboxylic acid component with a specified diamine component in equimolar amounts and subjecting the mixture to two-stage melt polymerization. CONSTITUTION:A dicarboxylic acid component comprising 30-60 pts.wt. aromatic dicarboxylic acid component and 70-40 pts.wt. aliphatic dicarboxylic acid component is mixed with a diamine component comprising an aliphatic diamine component in equimolar amounts, and the resulting mixture is subjected to homogeneous melt polymerization at 230-280 deg.C in the presence of water under a pressure of 20kg/cm G or more to obtain a precondensate. Subsequently, this precondensate is subjected to melt polymerization at a temperature in the range from the melting point of the finally obtained copolymer to the melting point +30 deg.C. Thus, an aromatic-ring-containing polyamide copolymer being lowly colored, being excellent in mechanical and thermal properties, having low water absorptivity and not turning pink even on water absorption can be obtained.
