Abstract: Copolymers comprising C14 to C50 olefins and at least two different olefindicarboxylic esters and optionally maleic acid or maleic acid derivatives. The olefindicarboxylic esters are firstly esters with linear C18- to C50-alkyl groups and secondly esters with short-chain linear, branched or cyclic alkyl groups, or esters with aromatic groups. The invention further relates to a process for preparing copolymers of this kind and to the use thereof as pour point depressant for crude oil, mineral oil and/or mineral oil products, preferably as pour point depressant for crude oil.

Abstract: 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 C6- to C20-alkyl radicals. The use of such polymeric compositions as pour point depressants for crude oils, mineral oils or mineral oil products.
