Mineral oil compositions with trace portions of additives contain as additive a comb polymer containing ester linkages, either based on a) ethylene-vinylester copolymers modified by hydroxy groups or glycidyl groups with molecular mass weight averages from 3000 to 50000 and an ethylene portion of 50 to 90 mass %, and b) partially imidated and/or partially esterified maleic anhydride copolymers, wherein in the comb polymer based on a) and b) the modified ethylene-vinylester copolymer component is connected by means of ester linkages to the partially imidated and/or partially esterified maleic anhydride copolymer component, or a comb polymer containing ester linkages based on c) ethylene-vinylester copolymers modified by acid and/or acid anhydride groups with molecular mass weight averages from 3000 to 50000 and an ethylene portion of 50 to 90 mass %, and d) polyalcohols partially esterified with C12-C40-monocarboxylic acids wherein in the comb polymer based on c) and d)the ethylene-vinylester copolymer component modified by acid and/or acid anhydride groups is connected by means of ester linkages with the polyalcohol component partially esterified with C12-C40-monocarboxylic acids. The mineral oil compositions are suitable as flowable media to be transported at low temperatures and as mineral oil fuels with high lubricity and flowability.

L'invention concerne des compositions d'huiles minérales à proportions réduites en additif, qui contiennent comme additif, un polymère en peigne contenant des liaisons esters, soit à base de : a) copolymères éthylène-vinylester modifiés par des groupes hydroxy ou glycidyle, présentant des indices rectifiés de masse molaire compris entre 3.000 et 50.000 et une proportion d'éthylène de l'ordre de 50 à 90 % en masse, ledit constituant copolymère éthylène-vinylester modifié étant combiné avec le constituant copolymère d'anhydride d'acide maléique partiellement imidisé et/ou partiellement estérifié, par l'intermédiaire de liaison ester, ou un polymère en peigne à base de liaison ester, soit à base de: c) copolymères éthylène-vinylester modifiés par des groupes d'acide et/ou par des groupes d'anhydride d'acide, présentant des indices rectifiés de masse molaire de l'ordre de 3.000 à 50.000 et une proportion en éthylène de l'ordre de 50 à 90 % en masse, ledit constituant copolymère-éthylène-vinylester modifié par acide et/ou par des groupes anhydride d'acide est combiné par l'intermédiaire de liaisons ester, avec le constituant polyalcool partiellement estérifié avec des acides monocarboxyliques C¿12?-C¿40?.
