The present invention relates to an aqueous pour point depressant dispersion composition comprising an ethylene vinyl acetate copolymer (EVA); a dispersing agent; a polyethoxylated nonionic surfactant, a low level of hydrocarbon solvent, water; optionally one or more of an aqueous freezing point depressant, a stabilizing agent, or a basic metal substance and a method to use said composition.

The instant disclosure provides a process for preparing a lubricant or fuel additive mixture where an oil of lubricating viscosity or fuel are blended with additives that are mixed via an acoustic mixer. The additives and oil of lubricating viscosity or fuel can mixed together or any component of the lubricant or fuel additive mixture can be mixed separately prior to mixing to form the final lubricant. The process provides for continuous mixing to form lubricant and/or fuel additive mixture final products.

A composition includes (a) a hydrocarbon fluid comprising less than 1000 ppm by weight of aromatics, a weight ratio normal paraffins/isoparaffins ranging from 0.2 to 1.0 and having an initial boiling point and a final boiling point in the range from 265° C. to 380° C., and (b) a copolymer derived from alpha-olefin monomers and vinyl acetate type monomers and optionally acrylate type monomers.

A composition comprising at least one fuel that is a diesel fuel, a biodiesel fuel, or combinations thereof and less than 100 ppm, less than 50 ppm (or less than 25 ppm, less than 10 ppm, 1 to 7 ppm, or 5 to 7 ppm) of an alkylene-coupled C.sub.10 to C.sub.60 (or C.sub.10 to C.sub.40, C.sub.14 to C.sub.32 or C.sub.24 to C.sub.28) alkylphenol; 25 to 500 ppm (or 50 to 500 ppm, or 150 to 450 ppm or 250 to 450 ppm, or 250 to 400 ppm) of a terpolymer; and 5 to 90 ppm, (or 10 to 70 ppm, to 60 ppm, or 10 to 55 ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group.

Methods of reducing the cold filter plugging point (“CFPP”) of a fuel, said method comprising adding the following components: less than 100 ppm, less than 50 ppm (or less than 25 ppm; less than 10 ppm, 1 to 7 ppm, or 5 to 7 ppm) of an alkylene-coupled C.sub.10 to C.sub.60 (or C.sub.10 to C.sub.40, C.sub.14 to C.sub.32 or C.sub.24 to C.sub.28) alkylphenol; 25 to 500 ppm (or 50 to 500 ppm, or 150 to 450 ppm or 250 to 450 ppm, or 250 to 400 ppm) of a terpolymer; and 5 to 90 ppm, (or 10 to 70 ppm, to 60 ppm, or 10 to 55 ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group.

Uses of a fuel additive composition to reduce the cold filter plugging point (“CFPP”) of a fuel, wherein the fuel additive composition comprises: 0.2 to 3 wt % of an alkylene-coupled C.sub.10 to C.sub.60 (or C.sub.10 to C.sub.40, C.sub.14 to C.sub.32 or C.sub.24 to C.sub.28) alkylphenol; 10 to 50 wt % of a terpolymer; and 2 to 10 wt % of hydrocarbyl-substituted amine detergent having at least one tertiary amino group; and an optional solvent.

This invention provides a wax inhibitor composition comprising A) the reaction product obtainable by reaction of i) a carboxylic acid containing an optionally substituted cycloaliphatic hydrocarbyl residue with ii) an alkylene polyamine, B) a polymeric wax inhibitor, and C) an organic solvent.

An additive composition for a diesel fuel, the additive composition comprising: (i) a first additive comprising one or more of: (a) the reaction product of a polycarboxylic acid having at least one tertiary amino group and a primary or secondary amine; (b) the reaction product of an α, β dicarboxylic acid or a derivative thereof and a primary amine; and (c) the reaction product of a polyamine and a fatty acid; and (ii) a second additive which is a terpolymer obtained by reacting monomers of: (x) an α-olefin; (y) an ester of an unsaturated alcohol; and (z) a third monomer different to (x) and (y) comprising an alkene functional group.

Diesel fuel compositions are provided that have unexpectedly beneficial cold flow properties. Methods for forming such diesel fuel compositions are also provided. The improved cold flow properties are achieved in part based on dewaxing of a distillate fraction of the composition. The improved cold flow properties are achieved further in part based on inclusion of a cold flow additive and fatty acid alkyl ester in the composition, such as fatty acid methyl ester.

The present invention relates to a novel copolymer, to processes for preparation thereof and to the use thereof.
