Abstract

PURPOSE: The membrane for selective separation having a good selection rate and separation efficiency, and further, a long life, which is constituted of the saponified substance of the copolymer of α-olefin and vinyl acetate, in which the content of α-olefin of the prescribed carbon number and the saponification degree of the vinyl acetate component are specified, as the main component.
