Abstract

Se trata de poliésteres y copoliésteres de cadena ramificada, que forman filamentos, con un peso molecular relativo de > 10.000, los cualesmediante incorporacion durante la condensacion de 50 - 500 ppm de uno o varios agentes para ramificacion de cadenas, anadidos durante la preparacion de lospoliésteres, que tienen la formula general (I), en la que n significa = 2-4, en los componentes de partida que forman poliésteres. Estos se adecuansobresalientemente para la hilatura rápida de hilos textiles e industriales con unas velocidades de enrollamiento de 2.500 - 10.000 m/min., a lo que siguenusuales procesos de estiramiento o procesos de texturizacion. Tambié se propone un procedimiento para preparar dichos poliésteres ycopoliésteres yla utilizacion de los mismos en la hilatura a velocidad del orden de 2.500 a 10.000 m/min.
