Abstract:
1. A copolyamide resin, comprising: i) a diamine component comprising two or more diamines; and ii) a dicarboxylic acid component, wherein the diamine component comprises 70 mol % or more of a xylylenediamine comprising 20 mol % or more of p-xylylenediamine, and the dicarboxylic acid component comprises 70 mol % or more of a straight-chain aliphatic dicarboxylic acid having 6 to 18 carbon atoms, and wherein a cast film formed by melting the copolyamide resin at a temperature 10° C. higher than the melting point of the copolyamide resin comprises particles having a major diameter of 50 μm or more in an amount of 1000 particles/g or less but more than 0, the particles comprising a polyamide having a melting point higher than that of the copolyamide resin by 20° C. or more when measured by a differential scanning calorimetry.
