    摘要： The invention relates to a copolyamide comprising at least two units corresponding to the following general formula: A/10,T in which: A is chosen from a unit obtained from an amino acid, a unit obtained from a lactam and a unit corresponding to the formula (Ca diamine).(Cb (cyclo)aliphatic diacid), with a representing the number of carbon atoms of the diamine and b representing the number of carbon atoms of the diacid, a and b each being between 4 and 36; 10,T denotes a unit obtained from the polycondensation of 1,10-decanediamine and terephthalic acid, characterized in that it has a polydispersity index, denoted by Ip, of less than or equal to 3.5, measured by gel permeation chromatography. The invention also relates to the process for preparing said copolyamide, a composition comprising this polyamide and also the use of this polyamide and of such a composition.

    摘要： The invention relates to a composition comprising: at least one polyamide (A); at least one copolymer (B) comprising polyamide blocks and polyether blocks; a single polyolefin (C), said polyolefin being a polyolefin functionalized by maleic anhydride units or by epoxy units, where the polyamide (A) comprises different units from the polyamide of the polyamide blocks. The invention also relates to objects manufactured from this composition and to the associated manufacturing process.
