PURPOSE:To obtain a polyamide composition having excellent heat-resistance, thermal discoloration resistance, tensile strength, tensile elongation, etc., and suitable as an automobile part such as body panel, sole of a shoe, etc., by compounding a low-melting polyamide, a high-melting polyamide and a rubber component at specific ratios. CONSTITUTION:The objective composition is produced by compounding (A) 5-70wt.% of a low-melting polyamide having a melting point of <200 deg.C (e.g. nylon 11 or nylon 12), (B) 15-85wt.% of a high-melting polyamide having a melting point of >=200 deg.C (e.g. nylon 6 or nylon 6, 6) and (C) 5-70wt.% of a rubber component having one or more functional groups selected from carboxyl group, hydroxyl group and epoxy group (e.g. acrylonitrile-butadiene copolymer) at a weight ratio (A/C) of 0.2-5. |
