Abstract: The invention relates to modified copolymers suitable as paraffin dispersants obtainable by reacting a copolymer of an ethylenically unsaturated bicarboxylic acid and/or a bicarboxylic derivative and a diketen of general formula (I) in which R and R are mutually independently hydrogen or C1-C30 alkyl with an amine of general formula (II) in which m = 0 to 100, n = 0 to 5 and x = 0 to 5, R , R and R are mutually independently hydrogen or a C1-C5 alkyl radical, and A is NR R or a C2-C30 alkoxy radical in which at least one of the substituents R or R is different from hydrogen and is a C1-C30 alkyl or alkenyl radical or a polyether radical (a) where R and R is hydrogen or C1-C5 alkyl and p = 1 to 100, with the proviso that A is NR R if n = 0, their production and use, and middle petroleum distillates containing these modified copolymers.

Abstract: The invention relates to a copolymer from the monomers of constituents A to C as indicated below and optionally D, the total weight of which amounts to 100 mol %: a) 20 to 80 mol % of at least one ethylenically unsaturated dicarboxylic acid or an anhydride, ester and/or amide thereof as constituent A; b) 1 to 79 mol % of at least one diketene of general formula (I), wherein R and R independently means hydrogen or C1-30-alkyl as constituent B; c) 1 to 79 mol % of at least one vinyl ester, (meth)acrylic acid alkyl ester, (meth)acrylnitrile or mixtures thereof as constituent C and d) 0 to less than 0.5 mol %, or when at least 20 mol % of constituent C is provided, 0 to 20 mol % of at least one other olefinically unsaturated monomer as component D. The inventive copolymer is used as a flow enhancer in petroleum middle distillates.
