Composite ester polyamide composition, lubricant composition, lubricant and method for producing composite ester polyamide composition

摘要

An object of the present invention is to provide a lubricant capable of exhibiting excellent lubrication performance and having excellent hydrolysis resistance. The present invention can be obtained by condensing a polyvalent amine containing at least two primary or secondary amino groups, a polyvalent carboxylic acid containing at least two carboxyl groups, and a monohydric alcohol having 4 or more carbon atoms. The present invention relates to a composite ester polyamide composition containing an ester polyamide. Furthermore, this invention relates to the manufacturing method of the lubricant composition containing a composite polyester composition, a lubricant, and a composite ester polyamide composition.
