Abstract

Procédé pour la préparation de fibres ayant une structure poreuse, fibres poreuse ainsi obtenues et leur utilisation. Ce procédé comprend : la préparation d'une solution ou d'une masse fondue d'une substance naturelle ou polymérisée ; l'incorporation dans la solution ou la masse fondue d'une substance liquide ou solide qui n'est pas miscible avec la solution ou est insoluble dans la solution; le filage du mélange ainsi préparé et l'élimination de la substance non miscible ou insoluble des filaments filés, par des moyens physiques ou chimiques. Utilisation des fibres très poreuses obtenues comme substrats pour des réactifs chimiques, pour l'insolubilisation de protéines et aussi comme tamis moléculaire.
