Additives for n-paraffin-containing lubricating oils, which additives are mixtures of acrylates containing (I) from 10 to 99 weight percent of polymers P1 composed of (a) esters of methacrylic acid and/or acrylic acid and linear C6 to C15 alcohols; (b) esters of methacrylic acid and/or acrylic acid and linear C16 to C30 alcohols; (c) esters of methacrylic acid and/or acrylic acid and branched C8 to C40 alcohols; (d) esters of methacrylic acid and/or acrylic acid and C1 to C5 alcohols; and (e) monomers having functional groups, the amount of (b) being at the most 5 mol percent; and (II) from 90 to 1 weight percent of polymers P2 composed of (a') esters of methacrylic acid and/or acrylic acid and linear C6 to C15 alcohols; (b') esters of methacrylic acid and/or acrylic acid and linear C16 to C30 alcohols; (c') esters of methacrylic acid and/or acrylic acid and branched C8 to C40 alcohols; (d') esters of methacrylic acid and/or acrylic acid and C1 to C5 alcohols; and (e') monomers having functional groups, the amount of (b') being between 10 and 70 mol percent; and a solvent therefor. |
