The invention relates to side-chain-modified copolymer waxes consisting of long-chain olefins, acrylic acid esters, acrylic acid and/or acrylic acid amides, said waxes being characterised in that they are produced from wax-like copolymers of long-chain α-olefins comprising between 18 and 60 C atoms, acrylic acid methyl esters, acrylic acid and/or acrylic acid amides, the carboxyl functionality thereof having been modified by chemical reaction with nucleophilic constituents. The invention also relates to a method for producing such copolymer waxes and to the use of the same.
