| abstract | The invention relates to a semi-crystalline copolyamide comprising at least two units corresponding to the following formula: X/Y where - the X unit is a crystalline unit obtained by polycondensation of a unit selected from a C6-C12 alpha,omega-aminocarboxylic acid, a C6-C12 lactam and a (Ca diamine).(Cb diacid) unit, where a is the number of carbon atoms of the diamine and b is the carbon number of the diacid, a and b being greater than or equal to 4; - the Y unit is a unit obtained by the polycondensation of a (Cd diamine).(Ce diacid) unit, where d is the number of carbon atoms of the diamine and e is the carbon number of the diacid, d being between 4 and 48 and e being between 6 and 48, the Cd diamine being selected from the aliphatic diamines, cycloaliphatic diamines and amine-terminated polyethers; - the copolyamide optionally having a piperazine content of between 0 and 18 mol % relative to the total number of moles of the components of the copolyamide; - the copolyamide not comprising ethylenediamine; - the copolyamide comprising from 30 to 99.5 mol % of unit X and from 0.5 to 70 mol % of unit Y; - the copolyamide having a viscosity in the molten state, measured according to standard ASTM D3236-88 (2009), of between 0.5 and 70 Pa.s at 200° C; - the copolyamide having a Tg below 0°C. The invention also relates to a method for preparing same and to the use thereof. |
