- ? - ABSTRACT OF THE DISCLOSURE New copolymers, mixtures thereof with poly(meth)acrylate esters and the use thereof for improving the cold flu- idity of crude oils Copolymers and the use thereof for improving the fluidity of crude oils. Copolymers of 50 to 99.9% by weight of a C14-C22-alkyl (meth)acrylate and 50 to 0.1% by weight of a comonomer of the formula 1 Image (1) in which R1 is hydrogen or methyl, R2 is a group of the formulae Image , Image , Image , Image , Image , -CH2-O-C2HF3 , Image or Image , R3 is C1-C80-alkyl, C2-C80-alkenyl, C5- or C6-cycloalkyl or -cycloalkenyl which can each be substituted by alkyl groups, or is aralkyl, alkaryl or the radical of a dimeric fatty acid, of maleic acid, of succinic acid or of a C6-C22-alkenylsuccinic acid, R4 is C1-C80-alkyl, C1-C80-alkenyl, C5- or C6-cycloalkyl or -cycloalkenyl which can each be substituted by alkyl groups, or is aralkyl or alkaryl, R5 is C6-C20 -alkyl, - ? - m is 2 or 3, n is a number from 1 to 30 and is a number from 2 to 20, and mixtures of such a copolymer with C14-C22-alkyl poly(meth)acrylates. These copolymers or their mixtures with C14-C22-alkyl poly(meth)acrylates are outstandingly suitable for improving the fluidity of crude oils. Those copolymers are also included here which contain a comonomer of the formula 1 in which R2 additionally can also be a group of the formula Image , Image or Image
