摘要： A hydrocarbon oil composition comprising a paraffinic hydrocarbon oil and as an additive, at least one linear polymer of carbon monoxide with one or more .alpha.-olefins having at least 10 carbon atoms per molecule said polymer comprising of substantially alternating monomer units of carbon monoxide and olefins is disclosed. Optionally, the composition may also contain one or more C.sub.9+ or less olefin polymer comprising of substantially alternating monomer units of carbon monoxide and olefins. This composition has and exhibits improved pour point, cloud point, and cold filter plugging point properties. These polymer additives are novel compounds, and a process for their synthesis is also disclosed.
