Title:
GAS SEPARATING MEMBRANE HAVING HIGH PERMEABILITY
Document Type and Number:
Japanese Patent JPS5942004
Kind Code:
A
Abstract:
PURPOSE: To improve the permeability, the ratio of the coefft. of permeability and processability of a permeable membrane by using poly(tertiary butyl acetylene) having the ratio of trans structure/cis structure in a specific range in forming said membrane.
CONSTITUTION: This gas separating membrane having high permeability is formed by using the poly(tertiary butyl acetylene) having the ratio of trans structure/cis structure in a 28/72W43/57 ratio. This separating membrane is capable of separating gas from a gaseous mixture such as air at, for example, a high coefft. of oxygen permeability and ratio of coeffts. of oxygen/nitrogen permeation, and has excellent processability for formation of a thin film.
