HYDROCARBON OIL COMPOSITIONS

摘要

Hydrocarbon oil compositions, containing a paraffinic hydrocarbon oil and as additives: a) one or more linear polymers of carbon monoxide with one or more olefins consisting at least in part of .alpha.-olefins having at least 10 carbon atoms per molecule (C10+ .alpha.-olefins) in which polymers on the one hand the units originating from carbon monoxide and on the other hand the units originating from the olefins occur in a substantially alternating way, and moreover one or more polymers selected from: b) polymers of one or more olefinically unsaturated compounds consisting at least in part of alkyl acrylates or alkyl methacrylates having at least eight carbon atoms in the alkyl group (C8+ alkyl esters), and c) polymers of ethene with one or more vinyl esters of saturated aliphatic monocarboxylic acids.
