Abstract
La présente invention concerne un procédé de préparation en continu d’un prépolymère de polyamide dont la viscosité en solution est comprise de 0,25 dl/g à 0,70 dl/g, telle que mesurée selon ISO 307 :2007 dans le m-crésol à 20°C, caractérisé en ce qu’il comprend une étape de polycondensation à partir d’un ou plusieurs monomères précurseurs de polyamide, la dite étape de polycondensation étant effectuée dans une extrudeuse comprenant au moins deux vis d’acheminement tournant de manière co-rotatives, le ou lesdits monomères étant préalablement introduits sous forme solide ou liquide sans mise en solution dans un solvant ou dans l’eau, et ladite étape de polycondensation étant effectuée sans extraction de l’eau formée au cours de ladite polycondensation.
