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.

Abstract:
The present invention aims to provide an aqueous dispersion that contains particles of a fluoropolymer at high concentrations and has a less variable pH, and in which aggregates are less likely to be generated even after the aqueous dispersion has been stored for a long time. The present invention relates to an aqueous dispersion, including: particles of a fluoropolymer having an average primary particle size of 0.1 to 0.5 µm in an amount of 50 to 70% by mass; a nonionic surfactant in an amount of 2 to 10% by mass based on the amount of the fluoropolymer; and ammonium lauryl sulfate in an amount of 0.0001 to 1% by mass based on the amount of the fluoropolymer, wherein an amount of a fluorine-containing anionic surfactant is less than 10 ppm.
