Zusammenfassung:Polymeric compositions obtainable by free-radical polymerization of at least two different alkyl (meth) acrylates in the presence of at least one ethylene-vinyl ester copolymer, the alkyl (meth) acrylates used being a mixture comprising alkyl (meth)acrylates having linear C12- to C60-alkyl radicals and different alkyl (meth)acrylates having linear C1- to C11-alkyl radicals and/or branched C4- to C60-alkyl radicals and/or cyclic C5- to C20-alkyl radicals. The use of such polymeric compositions as pour point depressants for crude oils, mineral oils or mineral oil products.
