摘要:
This invention provides hydrocarbon oil compositions comprising a major amount of a hydrocarbon oil and, as active ingredients, minor amounts of a copolymer of at least one n-(C₈-C₄₀-alkyl) (meth)acrylate with maleic anhydride, and at least one additive selected from the group consisting of a homopolymer or copolymer derived from an unsaturated hydrocarbon monomer, an ester and a wax anti-settling additive; additive concentrates containing the active ingredients and use of the latter in improving the cold flow properties of hydrocarbon oils.
