Abstract

Procedimiento para la produccion de hilos de polímeros de alta resistencia a la traccion baja deformacion permanente, caracterizado porque comprende los siguientes pasos: a) preparar una mezcla de: (i) un primer copolímero o polímero de poliolefina de peso molecular ultra alto, (ii) un segundo copolímero o polímero de poliolefina nanocompuesto con arcilla y (iii) un solvente de hilado no polar, b) alimentar la suspension resultante a través de un extrusor a una temperatura de por lo menos 180°C, causando la formacion de un gel, c) hilar el gel así obtenido en una hilera con una relacion entre longitud y diámetro (L/D) de por lo menos 15; d) enfriar el hilo a una temperatura por debajo de 2°C, e) retirar subsiguientemente el solvente de hilado no polar, y f) estirar el hilo así obtenido de modo de lograr un valor de resistencia a la traccion de por lo menos 18 cN/Dtex y un valor de deformacion permanente menor de 0,07% por hora, en donde el primer copolímero o polímero de poliolefina de peso molecular ultra alto tiene un peso molecular promedio en peso mayor de 2.000.000 g/mol y una polidispersidad de por lo menos 7, y el segundo copolímero o polímero de poliolefina nanocompuesto con arcilla se obtiene a través de polimerizacion in situ de una olefina y una arcilla en capas exfoliada, teniendo la poliolefina así obtenida un peso molecular promedio en peso de por lo menos 400.000 g/mol.
