Abstract: Novel sorbents comprising (a) an alumina component comprising alumina of the surface area of at least 20 and preferably 100 square meters per gram, and (b) a salt, or mixtures of salts, of an alkali or alkaline earth metal, especially oxides, hydroxides, carbonates, nitrates, acetates or aluminates of sodium and potassium, are outstandingly effective for the removal of nitrogen oxides and sulfur oxides from waste gas streams.

Abstract: A paper like butene-1 polymer sheet material is made by extruding a composition comprising (a) about 20 to 97% by weight of a butene-1 polymer having a molecular weight in excess of about 20,000, an isotacticity of at least about 25% and a butene-1 content of at least about 50% by weight, and (b) about 3 to 80% by weight of at least one normally solid filler insoluble in said polymer, to form a sheet, and stretching said sheet at least about 5% beyond its yield strain. The filler may be organic or inorganic and the sheet is preferably stretched at least about 20% beyond its yield point. The sheet is characterized by a novel surface appearance when scanned in an electron microscope, by dimensional stability and by approximately equal strengths in all directions as evidenced by a maximum tensile strength ratio of about 13:1 in mutually perpendicular directions.
