Abstract (en)

[origin: WO2018108534A1] Use of copolymers obtainable by - in a first reaction step (I) - copolymerization of (A) at least one ethylenically unsaturated mono-or dicarboxylic acid or derivatives thereof, preferably a dicarboxylic acid, (B) at least one a-olefin having from at least 12 up to and including 30 carbon atoms, (C) optionally at least one further aliphatic or cycloaliphatic olefin comprising at least 4 carbon atoms which is distinct from (B), and (D) optionally one or more further copolymerizable monomers distinct from the monomers (A), (B) und (C) and selected from the group consisting of (Da) vinyl esters, (Db) vinyl ethers, (Dc) (meth) acrylic esters of alcohols comprising at least 5 carbon atoms, (Dd) allyl alcohols or ethers thereof, (De) N-vinyl compounds selected from the group consisting of vinyl compounds of heterocycles containing at least one nitrogen atom, N-vinyl amides or N-vinyl lactams, (Df) ethylenically unsaturated aromatics, (Dg) α,β-ethylenically unsaturated nitriles, (Dh) (meth)acrylic amides and (Di) allylamines, followed by - in a second reaction step (II) - partial reaction of anhydride or carboxylic acid functionalities present in the copolymers obtained from (I) with at least one compound (E) containing at least one alcohol group and/or at least one amino group and - in a third reaction step (III) -hydrolysis of the anhydride functionalities present in the copolymer obtained from (II) and/or partial saponification of carboxylic ester functionalities present in the copolymer obtained from (II) as a diesel fuel additive.
