    Abstract: The present invention relates to surface-modified nanoparticulate metal oxides where the metal is chosen from the group consisting of aluminum, cerium, iron, titanium, zinc and zirconium, wherein the surface modification comprises a coating with a copolymer P comprising, as monomers, A) 1 to 99 mol % of a N-vinylamide N-vinylpyrrolidone and B) 99 to 1 mol % of a monomer comprising, per molecule, a free-radically polymerizable α,&bgr;-ethylenically unsaturated double bond and an anionogenic and/or anionic group, with the proviso that the copolymer P must comprise no further monomers chosen from the group consisting of C8-C30-alkyl esters of monoethylenically unsaturated C3-C8-carboxylic acids, N-alkyl- or N,N-dialkyl-substituted amides of acrylic acid or of methacrylic acid with C8-C18-alkyl radicals, or vinyl esters of aliphatic C8-C30-carboxylic acids.

    Abstract: A thermoplastic polymer mixture (I) containing a polyamide (II) and a polymer (III), where the melt viscosity, as measured at 280 deg C is 100-20,000 s-1 is at most 75% of the melt viscosity measured in accordance with ISO 1443 of polyamide (II) at 280 deg C, and the boundary surface tension between a melt of polyamide (II) and a melt of polyamide (III) at 280 deg C, measured in accordance with US patent 5,50,607 by the Spinning-Drop-Method is in the region of 0-10 mN/m. A thermoplastic polymer mixture (I) containing (wt.%): (a) a polyamide (II)(50-99.9), (b) a polymer (III)( 0.1-50), where the melt viscosity, as measured in accordance with ISO 1443 of polyamide (II) at 280 deg C over the whole Scherraten (sic) region is 100-20,000 s-1 is at most 75% of the melt viscosity measured in accordance with ISO 1443 of polyamide (II) at 280 deg C, and the boundary surface tension between a melt of polyamide (II) and a melt of polyamide (III) at 280 deg C, measured in accordance with US patent 5,50,607 by the Spinning-Drop-Method is in the region of 0-10 mN/m. Independent claims are included for: (1) a process for preparation of a fiber by spinning a melt of a thermoplastic polymer, using the above polymer mixture (I) as the thermoplastic polymer; (2) a fiber obtained by the above process; (3) a carpet containing the above fiber; and (4) flat structure textiles containing the above fiber.
