<p>A polymer composition and fiber or film 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 saturated hydrocarbon amine oxide. Also disclosed is a method for preparing a polyolefin fiber or film, which includes adding the above stabilizer system to an olefin polymer containing such an acid neutralizing agent. In a special embodiment, an unconventionally low amount of a saturated or unsaturated fatty acid may be present as a processing aid.</p> |
