PROBLEM TO BE SOLVED: To obtain a polyamide resin composition useful as a material capable of improving strength of a fused part of molding product prepared by fusing fabrication, by compounding an aromatic polyamide resin having a melting point within a specified temperature range with an aliphatic polyamide resin. SOLUTION: This composition comprises (A) a semiaromatic polyamide resin having 280-340 deg.C melting point (a polyamide resin composed of a component obtained by polycondensation of terephthalic acid and hexamethylenediamine as a main component, preferably a nylon 6T copolymer copolymerized with an aliphatic polyamide such as nylon 6 or nylon 66) and (B) a polyamide resin obtained from an aliphatic carboxylic acid or lactam, a polyamide resin obtained from an aliphatic diamine and an aliphatic dicarboxylic acid or an aliphatic polyamide resin which is a copolymer of the compounds (especially preferably nylon 6, nylon 6/66 copolymer) in the ratio of 30-99 wt.% of the component A and 1-70 wt.%, preferably 3-50 wt.% of the component B. |
