Abstract (en)

[origin: WO2018015667A1] The invention relates to the use of copolymers and additive concentrates containing such copolymers to improve the low-temperature properties of fuels, also referred to as cold-resistance properties, in particular the flow properties thereof during storage and/or use at low temperature. The invention also relates to the use of copolymers as an anti-sedimentation additive and the use of copolymers to expand the flow improving effect of the cold flow improver (CFI) by raising the cold filter plugging point (CFFP) of the fuel.
