Abstract

Blend membranes containing poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) and homopolymers of substituted <i>N</i>-phenmylmaleimides were prepared by casting from chloroform solutions of mixtures of the polymers. The polyimides were synthesized by the radical polymerization of dimethylamino, chloro, and bromo derivatives of <i>N</i>-phenylmaleimide. The membranes were characterized by permeabilities to oxygen and nitrogen; the permeability ratio O<sub>2</sub>/N<sub>2</sub> equaled to 5.3 - 6.8. Unlike transparent PPO membranes, PPO/polyimide membranes were cloudy. The phase structure of the membranes was examined by optical and scanning electron microscopy. The relation between gas transport properties and the structure of the membranes is discussed.
