Title (EN) PERFORMANCE ENHANCING ADDITIVES FOR FIBER FORMATION AND POLYSULFONE FIBERS
(FR) ADDITIFS POUR AMÉLIORER L'EFFICACITÉ POUR FORMATION DE FIBRES ET FIBRES DE POLYSULFONE
Abstract: front page image
(EN)Disclosed are methods for spinning hollow polyarylether polymer fiber, in particular using additives in the processes to form the polymeric fibers. The fibers produced can be formed into membranes with improved middle and/or higher molecular weight solute removal. Preferably, the polyarylether polymer fiber is a polysulfone fiber.
(FR)La présente invention concerne l'utilisation d'additifs dans des procédés pour former des fibres polymères. Ces fibres peuvent être transformées en membranes présentant une élimination améliorée de soluté de masse moléculaire moyenne et/ou supérieure.
