Composition (c) also can be prepared by blending, after polymerization, component (c)(3) with polymerized composition comprising components (c)(1) and (c)(2).

    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''-nitriloÄtriethyl-tris(3,3',5,5'-tetra-tert.butyl-1,1-biphenyl -2,2'-diyl)phosphiteÜ 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.
