Gas permeable membrane

Abstract

Abstract PURPOSE:To obtain a permeable membrane which has excellent gas permeability and is free from deterioration with age after use by incorporating metallic chelate molecules having oxygen affinity into substd. polyacetylene. CONSTITUTION:The mono- or di-substd. polyacetylene having a bulky substituent is used as a host high polymer. The metallic chelate which contains Mn, Fe, Co, Cu, etc., as the metal and consists of ligand of nitrogen, phosphorus, oxygen, etc., together therewith is used as the metallic chelate having the oxygen affinity. For example, porphyrin and phthalocyanine are preferable. The film of polyacetylene is impregnated with the soln. prepd. by dissolving such complexes into a suitable solvent, by which the complexes can be taken into the membrane. The membrane may also be formed by dissolving both together and casting such soln.
