Definitions

  • the present invention relates to the use of metallocene-catalyzed oligodecenes with a number-average molecular weight of 500 to 200,000 as components in lubricants, in particular in motor oils and gear oils, and to such lubricants themselves. Since some of these oligodecenes represent new substances, the invention relates to continue these new oligodecenes.
  • Hydrogenated short and medium chain oligoalkenes have long been used as components in synthetic lubricants, e.g. Motor oils, used. These are essentially di-, tri- and tetramers which are produced by oligomerization, for example using boron trifluoride as a catalyst and alcohols such as butanol or pentanol as promoters. However, this technology does not specifically lead to higher molecular weight oligomers terminated with vinylidene double bonds.
  • poly-1-olefins from C 3 - to co-olefins such as propene, 1-butene, 1-pentene or 1-hexene with a number average molecular weight of 300 to 10,000 are known, which by conventional Metallocene catalysis can be produced.
  • the 1-olefins mentioned are always used in a mixture with more volatile saturated and unsaturated hydrocarbons, for example a technical butane / butene stream or technical isobutene-containing butene streams (“raffinate 1/11” from the steam cracker) are used.
  • the poly-1-olefins obtained are also suitable, inter alia, as a constituent for lubricants.
  • EP-A 613 873 (2) describes metallocene-catalyzed oligomers made from linear ⁇ -olefins having 8 to 20 C atoms, e.g. technical 1-octene or technical 1-dodecene, with a number average molecular weight of 400 to 3000. According to (2), such oligomers are generally suitable as a base material for lubricants, but no longer with a number average molecular weight of 6000 or more.
  • WO-A 96/28486 (3) relates to copolymers of unsaturated dicarboxylic acids or their anhydrides and oligomers of 1-olefins having 3 to 14 carbon atoms, which can be prepared by metallocene catalysis.

  • GPC gel permeation chromatography
  • the engine oils remain more fluid; at high temperatures (operating temperature of the engine) they remain sufficiently viscous so that the lubricating film does not tear off.
  • (Fully) synthetic motor oils are to be understood in particular as those based on organic esters, synthetic hydrocarbons, poly- ⁇ -olefins and polyolefins (e.g. polyisobutene).
