摘要： Membrane in the form of a flat sheet, tube, or hollow fiber having a hydraulic permeability to water of 10 -100 ml/m 2 /h/mmHg, and having a diffusive permeability to chloride (Cl - ) of more than 10 cm sec x 10, preferably more than 12 cm/sec x 10, a diffusive permeability to vitamin B 12 of more than 2 cm/sec 10, preferably more than 3 cm/sec x 10, and a diffusive permeability to inulin of more than 0.5 cm/sec x 10, preferably more than 1.0 cm.sec x 10 -4 .
The membrane is prepared in a process involving the combined use of a high molecular weight swelling agent in the casting solution end partial evaporation of solvent prior to subjecting the membrane to gelling.摘要翻译： 膜为平板，管或中空纤维形式的膜，对水的水渗透性为10 -100ml / m 2 / h / mmHg，对氯化物的扩散渗透率（Cl - ）大于10厘米秒× 10，优选大于12厘米/秒×10，对维生素B12的扩散渗透性大于2厘米/秒10，优选大于3厘米/秒×10，对菊粉的扩散渗透率大于0.5厘米/秒 ×10，优选大于1.0cm.sec×10-4。 该膜是在涉及在流延溶液中结合使用高分子量溶胀剂并使膜进行胶凝之前部分蒸发溶剂的方法制备的。

摘要： Process for producing a semipermeable hollow fiber, which comprises extruding a solution of polymer to form a hollow fiber extrudate, while simultaneously injecting a center medium into the bore of the hollow fiber extrudate, and coagulating the so formed extrudate.
Gases and/or vapors are used as said center medium, for example air or components thereof.
The polymer is preferably chosen among block copolymers comprising at least one hydrophilic polymer block and at least one hydrophobic polymer block. A polyethyleneoxide-polycarbonate block copolymer is particularly preferred.摘要翻译： 制造半透空心纤维的方法，其包括挤出聚合物溶液以形成中空纤维挤出物，同时将中心介质注入中空纤维挤出物的孔中，并凝固如此形成的挤出物。 气体和/或蒸汽用作所述中心介质，例如空气或其组分。 聚合物优选选自包含至少一个亲水性聚合物嵌段和至少一个疏水性聚合物嵌段的嵌段共聚物。 聚环氧乙烷 - 聚碳酸酯嵌段共聚物是特别优选的。
