Abstract (en)

[origin: EP0471266A1] The invention relates to synthetic oils containing, in addition to conventional components, 5 to 100% by weight of cooligomers of (meth)acrylates and 1-alkenes, the cooligomers CM being composed of A) 0 - 75% by weight of at least one 1-alkene having 4 to 32 carbon atoms in the molecule, B) 20 - 100% by weight of at least one (meth)acrylate of the formula I <IMAGE> wherein R represents hydrogen or methyl and R1 represents a straight-chain or branched alkyl radical or a cycloalkyl radical having 4 to 32 carbon atoms in the alkyl radical and C) 0 - 65% by weight of a (meth)acrylate of the formula II <IMAGE> wherein R' represents hydrogen or methyl and R2 represents an alkyl radical which is substituted by at least one hydroxyl group and has 2 to 6 carbon atoms, or represents a radical <IMAGE> wherein R3 and R4 denote hydrogen or methyl, R5 denotes hydrogen or a straight-chain or branched alkyl radical having 1 to 40 carbon atoms and n denotes an integer from 1 to 60, with the proviso that, when n represents 1, R5 simultaneously represents a straight-chain or branched alkyl radical having 1-40 carbon atoms.
