Abstract

L'invention concerne un copolyamide semi-cristallin comprenant au moins deux motifs répondant à la formule suivante : X/Y dans laquelle -le motif X est un motif cristallin obtenu par la polycondensation d'un motif choisi parmi un acide alpha,omega-aminocarboxylique en C5 à C12, un lactame en C6 à C12 et une unité (diamine en Ca).(diacide en Cb), avec a représentant le nombre d'atomes de carbone de la diamine et b représentant le nombre de carbone du diacide, a et b étant supérieur ou égal à 4, -le motif Y est un motif obtenu par la polycondensation d'une unité (diamine en Cd).(diacide en Ce), avec d représentant le nombre d'atomes de carbone de la diamine et e représentant le nombre de carbone du diacide, d et e étant compris entre 24 et 48, la diamine en Cd et le diacide en Ce étant aliphatiques linéaires ou ramifiés, saturés ou insaturés, -le copolyamide ne comportant pas d'éthylène diamine, -le copolyamide comprenant de 30 à 99,5% en mole de motif X et de 0,5 à 70% en mole de motif Y, -le copolyamide présentant une viscosité à l'état fondu mesurée selon la norme ASTM D3236-88 (2009) comprise entre 0,5 et 100 Pa.s à 200°C, -le copolyamide présentant une Tg inférieure à 0°C. L'invention porte également sur son procédé de préparation et sur son utilisation.
