Abstract

Cold-stable petroleum middle distillates contain small quantities of polymers or copolymers which contain substantial fractions of units of formula I <IMAGE> or consist of these, in which R<1> and R<2> independently of one another are hydrogen or low-molecular alkyl or together form a tetramethylene radical and in which R<3> and R<4> are unbranched alkyl radicals having 14 to 24 C atoms. The additives effect very good dispersing and flow improvement.
