Abstract:
Composition including: (A) 50% to 95% of at least one semicrystalline polyamide of formula A/Z in which: A is an aliphatic repeating unit chosen from a unit obtained from the polycondensation of at least one amino acid and a unit obtained from the polycondensation of at least one lactam or a unit X.Y obtained from the polycondensation of at least one diamine, and of at least one dicarboxylic acid, and Z represents another polyamide and is included from 0 to 20%; (B) 5% to 50% of at least one semicrystalline copolyamide comprising amide units (Ba1) and including polyether units (Ba2), having a glass transition temperature (Tg) below 75° C.; (C) 0% to 20% by weight of fibres and/or fillers, (D) 0% to 20% of at least one impact modifier, (E) 0% to 5% of at least one additive, for the manufacture of a sports article.
