Copolymers comprising Cto Colefins and at least two different olefindicarboxylic esters and optionally maleic acid or maleic acid derivatives. The olefindicarboxylic esters are firstly esters with linear C- to C-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.

Copolymers comprising a-olefins and olefin dicarboxylic acid esters, production thereof, and use thereof as pour point depressants for crude oils, mineral oils, or mineral oil products

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 C- to C-alkyl radicals and different alkyl (meth)acrylates having linear C- to C-alkyl radicals and/or branched C- to C-alkyl radicals and/or cyclic C- to C-alkyl radicals. The use of such polymeric compositions as pour point depressants for crude oils, mineral oils or mineral oil products.
