Abstract
Mixed ester products obtained by treatment of a triglyceride under transesterification conditions with a polyoxyalkylene glycol and a high molecular weight dicarboxylic acid, such as polymer acids, are useful metal working fluids. The modified triglycerides exhibit enhanced thermal stability and can be used either in neat form or in solution, particularly with 40 SUS to 300 SUS mineral oils.
