A composition including a copolyamide and a cross-linked polyolefin The present invention relates to a composition including: 45 to 95% by weight of a semi-aromatic copolyamide containing at least two separate units having the following general formulation no. t, where a is selected from a unit obtained from an amino acid, a unit obtained from a lactam, and a unit having the formula (ca diamine) (cb diacid), and xt denotes a unit obtained from the polycondensation of a cx diamine and terephthalic acid, with x being the number of carbon atoms of the diamine in cx, said copolyamide having a polymolecularity index, mentioned lp, of less than or equal to 3.5 measured by permeation chromatography gel, and an amino chain termination content of between 0.020 mcg / g and 0.058 mcg / g; and 5 to 55% by weight of at least one cross-linked polyolefin. The invention also relates to a method for preparing said composition and the uses thereof. |
