Abstract

processo para a preparação de um filamento oco, uso de filamentos ocos, e, filamentos ocos. a invenção se refere a um processo para a preparação de um filamento oco (f) com base em um ou vários polímeros hiper-ramificados (p) dissolvidos e potencialmente um ou vários outros polímeros (fp), caracterizado em que o polímero hiper-ramificado (p) fundido ou dissolvido, ou a mistura do polímero hiper-ramificado (p) com o outro polímero (fp), é passado através de uma ou várias fieiras (s), em que a relação entre o comprimento (l) da matriz da fieira e o canal da matriz (delta-d) situa-se entre 0,1 e 9,5. o processo pode ser aplicado para o preparo de filamentos ocos de polieterssulfona hiper-ramificados (hpes).
