Performance enhancing additives for fiber formation and polysulfone fibers

The present invention relates to a method for spinning hollow polyarylether polymer fibers, in particular the use of additives in processes to form polymeric fibers. The fibers can be formed into membranes with improved middle and/or higher molecular weight solute removal. Preferably, the polyarylet...

Beschreibung
Zusammenfassung:	The present invention relates to a method for spinning hollow polyarylether polymer fibers, in particular the use of additives in processes to form polymeric fibers. The fibers can be formed into membranes with improved middle and/or higher molecular weight solute removal. Preferably, the polyarylether polymer fibers are polysulfone fibers. 本发明公开了用于纺丝中空聚芳醚聚合物纤维的方法，尤其是在方法中使用添加剂以形成聚合物纤维。制备的纤维可形成为具有改善的中等和/或更高分子量溶质去除的膜。优选地，所述聚芳醚聚合物纤维是聚砜纤维。
