Hollow-Fiber Membrane Made From A Polymeric Blend Comprising An Aromatic Sulfone Polymer And Polyoxazoline

Abstract

A hollow-fiber membrane. The hollow-fiber membrane is made from a polymeric blend comprising an aromatic sulfone polymer and polyoxazoline, wherein the polymeric blend comprises from 27 wt. % to 30 wt. % aromatic sulfone polymer, based on the total weight of the polymeric blend; wherein the hollow-fiber membrane comprises an inner surface facing towards its lumen, an outer surface facing outwards and an intermediate wall having a wall thickness; wherein the hollow-fiber membrane is an integrally asymmetric, permeable hollow-fiber membrane.
