Abstract
A polyamide resin composition having excellent low-temperature impact resistance and surface property, a polyamide resin composition for rotational molding and a rotational molded article using the same. The polyamide resin composition includes a component (A) in an amount of a parts by weight, which is an aliphatic polyamide having a relative viscosity ηr of less than 2.6 as measured according to JIS K6920 under the conditions of 96 wt % of sulfuric acid, 1 wt % of the polymer concentration, and 25° C.; a component (B) in an amount of b parts by weight, which is a modified polyolefin having a density of 0.895 g/cmor less as measured according to ASTM D1505; and a component (C) in an amount of c parts by weight, which is a non-modified polyolefin having an MFR value of 3.0 to 30 g/10 min as measured in a load of 2.16 kg at 190° C., and the polyamide resin composition satisfies the following equations: 50≤c/(b+c)×100≤70, and 10≤(b+c)/(a+b+c)×100≤40.
