摘要：
The present invention relates to cooling additives for middle distillates, containing A) at least one polyester of formula (A1) wherein one of the radicals R1 to R4 represents a linear C16-C40 alkyl or alkenyl radical and the remainder of the radicals R1 to R4 represent, independently of one another, hydrogen or an alkyl radical having 1 to 3 C atoms, R5 is a C—C bond or an alkylene radical having 1 to 6 C atoms, R16 is a hydrocarbon group having 2 to 10 carbon atoms, n is an integer from 1 to 100, m is an integer from 3 to 250, p is 0 or 1, and q is 0 or 1, B) at least one copolymer of ethylene and of at least one ethylenically unsaturated ester, the copolymer having a melt viscosity, measured at 140 DEG C., of at most 5000 mPas, and C) at least one organic solvent.
