Abstract

Procedure for obtaining polyamides, constituted by the chains of formula: ** (see formula) ** In number such that the viscosity of the polymer, determined at 25ºC on a 1% solution in metacresol, is between 0.5 and 1.5, characterized in that it comprises reacting the terephthalic acid or one of its esters of lower alcohols with dimethyl-3,4-hexamethylene diamine and further polycondensation of the reaction product.
