NOVEL BLOCK POLYESTER-ETHER GAS SEPARATION MEMBRANES

摘要

Gas separation membranes formed from polyester-polyether block copolymers which are useful for separating gases from gas mixtures. The membranes and processes are especially suited for separating polar gases from mixtures that contain polar and non-polar species. The novel membranes exhibit good permeability and permselectivity as well as durability, making them well suited for industrial applications such as removal of acid gases from natural gas and removal of carbon dioxide from synthesis gas.
