Abstract: Polymeric mist control materials, methods of forming polymeric mist control materials, and methods of using such materials for mist control are provided. The polymeric mist control additives are formed of molecules comprised predominantly of monomers that confer high solubility in fuel and include associative groups that attract each other in donor-acceptor manner, and are incorporated such that multiple associative groups are in close proximity (“clusters”), such that the clusters are separated by very long non-associative sequences.

Abstract: Copolymers comprising C14 to C50 olefins and at least two different olefindicarboxylic esters and optionally maleic acid or maleic acid derivatives. The olefindicarboxylic esters are firstly esters with linear C18- to C50-alkyl groups and secondly esters with short-chain linear, branched or cyclic alkyl groups, or esters with aromatic groups. The invention further relates to a process for preparing copolymers of this kind and to the use thereof as pour point depressant for crude oil, mineral oil and/or mineral oil products, preferably as pour point depressant for crude oil.

Abstract: Fouling components within a fluid may be prevented from accumulating when an additive contacts the fluid, e.g. by coating the wellbore with the additive prior to the production of the fluid or adding the additive directly to the fluid, etc.. The additive may include, but is not limited to, a block copolymer having at least two components. The first component may be a charged monomer, and the second component may be a long chain fatty alcohol acrylate monomer. In one alternative embodiment, the fluid may be an oil-based fluid produced through a wellbore or an oil-based wellbore fluid, and the fouling components may be or include, but are not limited to, wax, paraffins, asphaltene, resins, and combinations thereof.

Abstract: The present invention concerns the use, for lowering the cold filter plugging point of a fuel composition, of one or more crosslinked polymers comprising at least one unit of the following formula (I): in which R1 represents a hydrogen atom or a methyl group; E represents —O—CO—, or —CO—O— or —NH—CO— or —CO—NH—; and G represents a C1 to C34 alkyl group; said copolymer having a crosslinking rate of between 0.5 mol % and 30 mol %. The invention also concerns additive compositions containing such a polymer, and fuel compositions with such polymers as additives, in combination with a cold flow improver (CFI) chosen from the copolymers and terpolymers of ethylene and vinyl and/or acrylic ester(s).

Abstract: A copolymer obtained by copolymerization of at least: an apolar monomer (ma) with the following formula (I), where u=0 or I, w=0 or I, E=-0- or —NH(Z)—, or —O—CO—, or —NH—CO— or —CO—NH—, wherein Z is H or an alkyl group, and G is a group selected among an alkyl, an aromatic ring and an arylalkyl; and a polar monomer (mb) selected among those of the following formula (II), wherein t=0 or I, Q is selected among the oxygen atom and the —NR′— group, wherein R′ is selected among a hydrogen atom and hydrocarbon chains, and R is a hydrocarbon chain substituted by at least one quaternary ammonium group and optionally one or more hydroxyl groups. The invention also relates to the use of such a copolymer as a detergent additive in a liquid fuel of an internal combustion engine.
