Abstract

PURPOSE: To provide a membrane excellent in hot water resistance, by crosslinking a micro-porous membrane or semipermeable membrane made of material obtained by saponification of ethylene-vinyl acetate type copolymer with a compound having more than two aldehyde groops, which is less subjected to change in size and is high in its permeation speed and excellent in compression resistivity.
