    Abstract: Petroleum distillates with improved properties contain minor amts. of a conventional ethylene-based flow improver (I) and a copolymer (II) comprising 10-95 mol.% of one or more 1-26C alkyl (meth)acrylates and 5-90 mol.% of one or more ethylenically unsatd. dicarboxylic acids or anhydrides, post-reacted with one or more primary or sec. amines to form the corresp. monoamide or amide/ammonium salt. (I):(II) wt. ratio is 40-95:60-5. - Pref. (I) is a copolymer of ethylene with vinyl acetate, vinyl propionate or ethylhexyl acrylate. (II) is a copolymer of 40-95% lauryl acrylate or 8-18C alkyl acrylate and 5-60% maleic anhydride, post-reacted with di(hydrogenated tallow) amine (DHTA), behenylamine or n-octadecylamine. (II) is opt. grafted onto (I). The distillates contain 50-5,000 ppm (I)+(II).
