An object of the present invention is to provide a lubricant having excellent lubrication performance. Further, another object of the present invention is to produce a polyester composition having a small load on an environment and mass productivity. The present invention relates to a production method for a complex polyester composition including a step of obtaining a complex polyester composition by condensing polyhydric alcohol, polycarboxylic acid having at least two carboxyl groups and carbon atoms of greater than or equal to 5, monohydric alcohol having at least one oxyalkylene group in the absence of a solvent, in which a component having a weight average molecular weight of less than or equal to 1300 in a GPC chart of the complex polyester composition is less than or equal to 43 area%. Further, the present invention relates to a complex polyester composition, a lubricant composition, and a lubricant.
本发明的一个目的是提供一种润滑性能优异的润滑剂。此外,本发明的另一个目的是生产一种对环境负荷小、生产效率高的聚酯组合物。本发明涉及一种复合聚酯组合物的生产方法,包括以下步骤:在无溶剂的情况下,通过缩合多元醇、具有至少两个羧基且碳原子数大于或等于 5 的聚羧酸、具有至少一个氧亚烷基的一元醇来获得复合聚酯组合物,其中,在复合聚酯组合物的 GPC 图中,重量平均分子量小于或等于 1300 的组分的面积%小于或等于 43。此外,本发明还涉及一种复合聚酯组合物、一种润滑剂组合物和一种润滑剂。
