Abstract
(EN)
Provided are: a polyamide resin composition which suppresses mold stains during molding and from which a molded product having excellent color tone can be produced; a molded product; a method for producing the molded product; and an antioxidant. This resin composition comprises: a polyamide resin composed of a diamine-derived constituent unit and a dicarboxylic acid-derived constituent unit, wherein 70 mol% or more of the diamine-derived constituent unit is derived from a compound represented by formula (1) and 70 mol% or more of the dicarboxylic acid-derived constituent unit is derived from an α,ω-linear aliphatic dicarboxylic acid having 8-12 carbon atoms; and a compound represented by formula (1), wherein the content of the compound represented by formula (1) is 3-100 mass ppm of the resin composition. In formula (1), R1 and R2 are each independently an alkyl group having 1-4 carbon atoms, and n1 and n2 are each independently an integer of 0 to 4. Formula (1)

L'invention fournit une composition de résine polyamide qui est telle que la salissure de matrice est inhibée lors de son moulage, et qui permet de fabriquer un article moulé d'une excellente teinte. L'invention fournit aussi un article moulé ainsi qu'un procédé de fabrication de celui-ci, et un antioxydant. Plus précisément, l'invention concerne une composition de résine qui contient : une résine polyamide qui est configurée à partir d'une unité constitutionnelle dérivée d'un diamine, et d'une unité constitutionnelle dérivée d'un acide dicarboxylique, 70% en moles ou plus de l'unité constitutionnelle dérivé d'un diamine, étant dérivée d'un composé représenté par la formule (1), et 70% en moles ou plus de l'unité constitutionnelle dérivée d'un acide dicarboxylique, étant dérivé d'un acide α,ω-dicarboxylique aliphatique à chaîne droite de 8 à 12 atomes de carbone ; et un composé représenté par la formule (1). La teneur en composé représenté par la formule (1) est comprise entre 3 et 100ppm en masse de ladite composition de résine. Dans la formule (1), R et R représentent chacun indépendamment un groupe alkyle de 1 à 4 atomes de carbone, et n1 et n2 sont chacun indépendamment un nombre entier de 0 à 4. Formule (1)
