    摘要: The invention relates to additives for improving the flowability of mineral oils, containing: A) 1-40 wt. % of at least one copolymer, which is oil-soluble and improves the cold flow properties of mineral oil, selected from A1) copolymers consisting of 80 to 96.5 mol % ethylene and 3.5-20 mol % vinyl esters of carboxylic acids with 1-20 C atoms and/or (meth)acrylic acid esters of alcohols with 1-8 C atoms, and A2) homopolymers or copolymers of esters, containing C10-C30 alkyl radicals, of ethylenically unsaturated carboxylic acids with up to 20 mol % of other olefinically unsaturated compounds, B) 20-80 wt. % of at least one poly-alpha-olefin with a molecular weight of 250-5000, derived from monoolefins with 3-5 C atoms, and C) 5-70 wt. % of at least one organic acid selected from C1) alkylphenol-aldehyde resins of formula (1), wherein R1 and R2 independently designate H or alkyl radicals with 1-30 C atoms, but both radicals do not at the same time signify H, n represents an integer of 3-50, and R3 represents H or an alkyl radical with 1-4 C atoms, and C2) aliphatic and/or aromatic sulfonic acids of formula R18—SO3H, wherein R18 stands for C6-C40-alkyl, C6-C40-alkenyl, or an alk(en)yl aryl radical which has 1, 2, 3 or 4 aromatic rings and 1, 2, 3 or 4 alkyl or aryl radicals with respectively 6-40 C-atoms.
