Abstract: The present invention relates to a copolymer obtainable by copolymerization of(A) at least one unsaturated dicarboxylic acid or derivatives thereof, (B) at least one α-olefin having from at least 6 up to and including 20 carbon atoms, (C) optionally at least one C3- to C20-alkyl ester of acrylic acid or methacrylic acid or a mixture of such alkyl esters and (D) optionally one or more further copolymerizable monomers other than monomers (A), (B) and (C), with a molar incorporation ratio of (A):(B):(C):(D) of 1:0.5 to 2.0:0 to less than 0.5:0 to 0.1 followed by the reaction with at least one dialkylamine (E), where the two alkyl radicals in the at least one dialkylamine (E) are independently alkyl radicals having at least 17 up to 30 carbon atoms.

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.
