  • Use of polymethylalkanes as biodegradable base oils in lubricants and functional fluids
    Patent number: 5366658
    Abstract: The invention relates to the use of polymethylalkanes having terminal methyl groups and methylene and ethylidene groups of the formula I ##STR1## in which the total number of C atoms n+2 m+2 is 20 to 100 and the ratio of the methyl and methylene groups to the ethylidene groups is 3 to 20:1 and the ethylidene groups are always separated by at least one methylene group, as biodegradable base oils for lubricants and functional fluids. Suitable polymethylalkanes are obtained by oligomerization of .alpha.,.omega.-diolefins, for example in particular according to P 41 19 332.6, or by pyrolysis of ethene/propane copolymers and subsequent hydrogenation in each case. The polymethylalkanes can be combined with conventional additives and other degradable or non-degradable base oils.
