Abstract

Process for obtaining poly-para-phenyleneterephthalamide and its copolymers of inherent viscosity of at least 2, characterized in that it comprises polycondensing terephthaloyl chloride, para-phenylenediamine and optionally other reagents leading to copolyamides in a substantially anhydrous reaction medium constituted by 30-98% ; by weight of hexamethylphosphatidamide and 70-2%; in weight of a γ-lactone.
