Abstract

PURPOSE:To make hollow, semipermeable composite membrane which shows no decrease in water permeability after hot-water treatment, by burying a core material e.g. plaited cord in a polymer soln. in such a manner that the core material is present near the interface between the soln. and a coagulating liq. in order to coagulate the polymer.
