Abstract: 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.
