Definitions
- the invention relates to the use of polymers which contain an ⁇ -olefin, a vinyl ester and an ester of an ⁇ , ß-unsaturated carboxylic acid in copolymerized form, as an additive for fuel oils and lubricants and especially as a cold flow improver in fuel oils; the fuel oils and lubricants additized with these polymers; and additive packages containing such copolymers.
- Paraffinic wax-containing mineral oils such as middle distillates, diesel and fuel oils
- Paraffinic wax-containing mineral oils show a significant deterioration in the flow properties when the temperature is lowered.
- the reason for this lies in the crystallization of longer-chain paraffins occurring from the temperature of the cloud point, which form large, platelet-shaped wax crystals.
- These wax crystals have a sponge-like structure and lead to the inclusion of other fuel constituents in the crystal composite. The appearance of these crystals quickly leads to the bonding of fuel filters both in tanks and in motor vehicles. At temperatures below the pour point (PP), finally, no more flow of fuel takes place.
- fuel additives have been added in small concentrations for a long time, often consisting of combinations of nucleators for the early formation of microcrystalline paraffins with the actual cold flow improvers (also referred to as CFI or MDFI). These in turn show similar crystallization properties as the paraffins of the fuel, but prevent their growth, so that a passage of the filter is possible at significantly lower temperatures compared to the unadditivated fuel.
- CFI Cold Filter Plugging Point
- WASA wax anti-settling additives
- Cold flow improvers are added in amounts of about 50 to 500 ppm, depending on the nature of the base fuel and the additive.

These should be suitable as pour point improvers of mineral oil distillates.
