Abstract
There is disclosed an inorganic reinforced polyamide resin compositions obtainable by melt kneading of (A) a crystalline polyamide rein, (B) a semi-aromatic amorphous polyamide resin, and (C) an inorganic reinforcing material, wherein the relative viscosity of 96% sulfuric acid solution of the composition is 2.1 or lower and wherein the crystallization temperature (TC2) of the composition as measured with a temperature drop by differential scanning calorimetry (DSC) is 180° C. or lower. The inorganic reinforced polyamide resin composition can provide shaped articles having satisfactory strength and rigidity without deteriorating their appearances and further having excellent coating properties and weathering resistance, and requires a mold temperature of 100° C. or lower in the preparation of shaped articles.
