Abstract: The process for separating a gaseous mixture containing at least one of carbon dioxide, oxygen and hydrogen sulfide into a fraction being enriched in at least one of these and a fraction being correspondingly depleted in at least one of these, the process comprising contacting the gaseous mixture with a semipermeable membrane, is improved by using a membrane constructed from at least one ring-substituted poly(arylene oxide) polymer. For example, carbon dioxide is efficiently separated from a gaseous mixture of carbon dioxide and methane, such as natural gas, by contacting it with a membrane constructed from a ring-brominated poly(2,6-dimethyl-p-phenylene oxide) polymer.

Abstract: Certain physical properties, such as heat-distortion temperature and flexural modulas, of certain commercially available thermoplastic resins such as vinyl chlorides, polyolefins, polystyrenes, polyesters, polycarbonates etc. are improved by blending with polyindene or coumarone-indene resins. These blends find the same use as for the resins and may be employed in making pipe, containers, fibers, sheets, films etc.

Abstract: A novel composite high-nitrile fiber in which the polymers are arranged in a sheath core type configuration. One polymer of the composite filament comprises a solventless, waterless, melt-processable acrylonitrile olefinically unsaturated polymer and the other polymer of the composite filament comprises an organic polymer. Either polymer can be employed as the sheath or the core component of the composite filament.
