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 of A) 60 to 99 mol % of an N-vinyllactam and B) 1 to 40 mol % of a monomer chosen from the group of b 1 ) C 8 -C 30 -alkyl esters of monoethylenically unsaturated C 3 -C 8 -carboxylic acids b 2 ) N-alkyl- or N,N-dialkyl-substituted amides of acrylic acid or of methacrylic acid with C 8 -C 8 -alkyl radicals, or b 3 ) vinyl esters of aliphatic C 8 -C 30 -carboxylic acids, or mixtures of these monomers.

Abstract: The use of polyacrylic acid (I) with an average mol. wt. (M w) of 5000-30000 and with end groups containing sulfur and at least 2 carbon atoms, which is at least partly neutralised with alkali metal hydroxide or ammonia, as auxiliary material for the wet-milling of calcium carbonate. Independent claims are also included for finely-divided suspensions of CaCO 3 containing 0.1-2 wt% (I), obtained by wet-milling in presence of (I).
