Polyamide resin composition, and polyamide resin composition and rotational molded article for rotational molding using the same

摘要

The present invention provides a polyamide resin composition excellent in low-temperature impact resistance and surface properties, and a polyamide resin composition for rotational molding using the same and a rotational molded article. In the polyamide resin composition according to the present invention, according to JIS K6920, 96 parts by weight of sulfuric acid, 1% by weight of polymer concentration, and an aliphatic polyamide having a relative viscosity ηr of less than 2.60 measured under conditions of 25 ° C, a part by weight, ASTM D1505 The modified polyolefin having a density of 0.895 g / cm 3 or less measured according to b parts by weight, and an unmodified polyolefin having an MFR value of 3.0 to 30 g / 10 min, measured at a load of 2.16 kg at 190 ° C., includes c parts by weight, 50≤ c / (b + c) × 100≤70 and 10≤ (b + c) / (a + b + c) × 100≤40 are satisfied.
