Abstract (en)
[origin: WO2008124265A2] The present invention relates to polyester polyol lubricant compositions, some of which are capped, that include two or more chemically linked ester moieties, at least one of which derives from a seed or vegetable oil, and their preparation. The compositions have a pour point temperature of -10° centigrade or less without a pour point depressant and a viscosity at 25° centigrade within a range of 40 centipoises (0.04 pascal second) to 2000 centipoises (2 pascal seconds) when they either lack an initiator moiety or include an initiator moiety other than a dendritic initiator moiety, and a pour point temperature of -5° centigrade or less without a pour point depressant and a viscosity at 25° centigrade within a range of 40 centipoises (0.04 pascal second) to 8000 centipoises (8 pascal seconds) when they include a dendritic initiator moiety. The present invention also relates to a process for removing at least a portion of saturates from said compositions.
