Abstract (en)
[origin: WO2016138939A1] Lubricant composition comprising a polyisobutene polymer having a number average molecular weight of 300-5000 g/mol and at least 60 mol % terminal double bonds based on the total number of double bonds in the polymer, and an ester component and/or an alkylated naphthalene compound having kinematic viscosity in the range of 2 to 15mm2/s at 100°C.
