Abstract

Se proporciona un filamento esencialmente continuo y biodegradable. El filamento contiene un primer componente formado de por lo menos un poliéster de derretido alto y un segundo componente formado de por lo menos un poliéster de derretido bajo. El poliéster de punto de derretido bajo es un copoliéster alifático-aromático formado mediante el mezclado con derretido de un polímero y un alcohol para iniciar una reacción de alcoholisis que resulta en un copoliéster teniendo uno o más grupos terminales de hidroxialquilo o de alquilo. Mediante el selectivamente controlar las condiciones de alcoholisis (por ejemplo concentraciones de alcohol y copolímero, catalizadores, temperatura, etc.), un copoliéster alifático-aromático modificado puede ser logrado el cual tiene un peso molecular más bajo que el polímero alifático-aromático de inicio. Tales polímeros de peso molecular más bajo tienen la combinación de un índice de flujo de derretido más alto y una viscosidad aparente más baja la cual es útil en la formación de filamentos esencialmente continuos.
