PURPOSE: To improve the flex resistance at low temperatures while maintaining a high cycle rate, i.e., without any reduction in productivity. CONSTITUTION: This composition is obtained by mixing a polyamide resin, preferably a poly-ε-caprolactam having a relative viscosity of 2.3 to 3.5, with 0.05-0.25wt.% potassium iodide and, if necessary, 0.005-0.1wt.% inorganic nucleating agent.
