  • Additive mixture as component of a mineral oil composition
    Patent number: 7776801
    Abstract: An additive mixture as component of a composition of mineral oil as main component and trace portions of an additive mixture containing the additive components a) ethylene-vinylester copolymers modified by polar groups with molecular mass weight averages from 3000 to 50000 and an ethylene component of 50 to 90 mass %, and b) C2-C6-oxyalkyl-bridged C12-C40-monocarboxylic acids, and/or c) partially and/or completely imidated copolymers of unsaturated C4-C20-dicarboxylic acid anhydrides and vinyl aromatics and/or C2-C36-?-olefins, whereby the content of the additive mixture in the mineral is 0.005 to 1 mass %. The compositions are suitable as flowable media to be transported at low temperatures and as mineral oil fuels with high lubricity and flowability.
