Abstract: Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions that can be used when the non-polar composition is in a flow, and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone with a longest span having a molecular weight that remains substantially unchanged under the flow conditions and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

(b) 5 to 25% by mass, based on the mass of the composition, of an oil-soluble or oil-dispersible alkali metal or alkaline earth metal salicylate detergent, or a mixture of two or more oil-soluble or oil-dispersible alkali metal or alkaline earth metal salicylate detergents;
(c) 0.1 to 10% by mass, based on the mass of the composition of one or more oil-soluble or oil-dispersible ashless dispersants; and optionally,
(d) 0.1 to 10% by mass, based on the mass of the composition of a polyalkylene-substituted succinic anhydride.

Abstract: The cold flow of middle distillate fuels may be improved by adding an effective improving amount of one or more alpha-olefin compositions. The compositions include, but are not necessarily limited to, polymers of alpha-olefins per se, copolymerized or grafted alpha-olefins with maleic anhydride, acrylic acid, vinyl acetate, alkyl acrylates, methacrylic acid, and/or alkyl methacrylates. These resulting copolymers or grafted polymers may be blended with alkylphenol-formaldehyde resins, which in turn may be blended with ethylene-vinyl acetate (EVA) copolymer. In a non-limiting example, the cold filter plugging point (CFPP) may be synergistically improved as compared with the expected additive effect of using the components separately.
