摘要:
An object of the present invention is to provide a lubricant which has excellent lubrication performance and is able to exhibit excellent lubrication performance even when under extreme pressure conditions. The present invention relates to a complex polyester composition containing polyester obtained by condensing polyhydric alcohol having at least two hydroxyl groups, a dicarboxylic acid having 44 carbon atoms, and monohydric alcohol. Further, the present invention relates to a lubricant composition containing the complex polyester composition, and a lubricant and a production method for a complex polyester composition.
