Claims24

Dependent claims

A lubricating oil composition comprising a biobased base oil, wherein the biobased base oil has the molecular structure:

wherein, [B] is a biobased hydrocarbon repeating unit;
[P] is a non-biobased hydrocarbon repeating unit,
n is greater than 1, and m is less than 4;
the stereoscopic arrangement of [B] and [P] is linear, branched or cyclic;
the sequential arrangement of [B] and [P] is block, alternating or random;
the molecular weight of the biobased base oil is in range of 300 g/mol to 1500 g/moL.
