Abstract: A polymer composition and fiber, film and fabric prepared therefrom. The composition contains (i) an acid neutralizing agent other than a metallic salt of a saturated or unsaturated fatty acid, (ii) a processing aid comprising a metallic salt of a saturated or unsaturated fatty acid, the metallic salt of a saturated or unsaturated being present in a maximum amount of 200 ppm, a stabilizer system containing (a) a phosphite selected from the group consisting of 2,2′,2″-nitrilo[triethyl-tris(3,3′,5,5′-tetra-tert.butyl-1, 1-biphenyl-2,2′-diyl)phosphite] and tris(2,4-di-tert-butylphenyl) phosphite; and (b) a N,N-dialkylhydroxylamine. Also disclosed is a method for preparing a polyolefin fiber, film or fabric which includes (A) incorporating the above additives into an olefin polymer, thereby producing a stabilized polyolefin polymer; and (B) extruding the stabilized olefin polymer through a die, thereby producing a olefin polymer fiber or film.

Abstract: A polymer composition and fiber, film or sheet prepared therefrom, which contains (i) an olefin polymer containing an acid neutralizing agent other than a metallic salt of a saturated or unsaturated fatty acid, and ii) a stabilizer system distributed throughout the polymer, the stabilizer system including (a) a phosphite selected from 2,2',2"-nitrilo?triethyl-tris(3,3',5,5'-tetra-tert.butyl-1,1-biphenyl-2,2' -diyl)phosphite! and tris(2,4-di-tert-butylphenyl) phosphite; and (b) a N,N-dialkylhydroxylamine. Also disclosed is a method for preparing a polyolefin fiber, film or sheet, which includes adding the above stabilizer to an olefin polymer containing an acid neutralizing agent other than a metallic salt of a saturated or unsaturated fatty acid, thereby producing a stabilized olefin polymer; and extruding the stabilized olefin polymer through a die.
