COMPOSITION CONTAINING A SEMI-AROMATIC COPOLYAMIDE, A POLYOLEFIN AND A COPPER HEAT STABILIZER, PREPARATION THEREOF AND USES THEREOF

摘要

The invention relates to a composition comprising - from 10% to 36% by weight of at least one polyolefin, - from 0.05% to 0.30% by weight of at least one copper heat stabilizer, wherein the copper heat stabilizer is a mixture of potassium iodide and copper iodide, and - at least one predominant semi-aromatic copolyamide comprising at least two distinct units corresponding to the following general formula: A/X.T in which: A is chosen from at least one unit obtained from an amino acid, at least one unit obtained from a lactam and at least one unit corresponding to the formula (Ca diamine).(Cb diacid), and the mixtures thereof, X.T denotes a unit obtained from the polycondensation of a Cx diamine denoted X and of terephthalic acid denoted T, the weight percentages being given relative to the total weight of the composition.
