Selectively Permeable Polymers and Gas-separation Membranes: Structure and Transport Properties

The relationship between the permeability coefficients and the sorption and diffusion properties of highly elastic and vitreous polymers has been examined. The concept of free volume can be used to interpret the characteristics of transport not only in highly elastic but also in vitreous polymers. The properties are discussed of the basic polymeric materials of gas-separation membranes; heterophase polymeric systems such as block copolymers and polymers with liquid-crystalline additives and additives undergoing specific interaction, and also quasi-liquid membranes with components facilitating the transport of gases.
