| abstract |
The present invention relates to a composition comprising: Semi-aromatic copolyamides comprising from 45% to 95% by weight of at least two separate units having the formula: A / XT {A is selected from units obtained from amino acids, units obtained from lactams and units having the formula (Ca diamine). (Cb diacid); XT represents a unit obtained from the polycondensation of Cx diamine and terephthalic acid, x represents the number of carbon atoms in the Cx diamine}, The copolyamide has a polydispersity index, expressed as Ip, of 3.5 or less, as determined by gel permeation chromatography, Having an content of amine chain ends of 0.020 meq / g to 0.058 meq / g; And From 5% to 55% by weight of at least one crosslinked polyolefin. The invention also relates to a process for the preparation of the composition and to the use thereof. |
