The invention relates to comb polymers based on olefin copolymer macromonomers. The comb polymers are obtained by hydrogenated olefin copolymer macromonomers of the formula I <IMAGE> in which R ': for hydrogen or methyl; R1: for the organic residue of an organolithium compound [A] for a segment formed by 1,4-addition of butadiene optionally substituted with a C1-C6-alkyl residue, [A '] for a segment formed by vinyl addition of optionally with a C1 - C6-alkyl-substituted butadiene and n + m represents an integer from 10 to 3000, with (meth) acrylic ester monomers of the formula II <IMAGE> in which R ': represents hydrogen or methyl and; R2: stands for an alkyl radical with 1 to 26 carbon atoms copolymerized in radical polymerization. |
