The invention comprises shock-resistant injected parts consisting of a polyamide resin base (A) and a dispersed phase where the particles have an average diameter by number of over 0.4µ and an average diameter by volume of over 1µ, such that over 50% of the particles by volume are greater than 1µ. The dispersed phase may consist of a mixture of at least one ethylene copolymer (B) and an unsaturated epoxide and at least one polyolefin (C).
L'invention concerne des pièces injectées résistant au choc à base de résine polyamide (A) et d'une phase dispersée dont les particules ont un diamètre moyen en nombre supérieur à 0,4 µm, un diamètre moyen en volume supéfieur à 1 µm et telle que plus de 50% en volume des particules sont supérieures à 1 µm. La phase dispersée peut être constituée d'un mélange comprenant au moins un copolymère (B) de l'éthylène et d'un époxyde insaturé et d'au moins une polyoléfine (C).
