GREASE THICKENING AGENT

Abstract

The present disclosure provides a polyamide grease thickening agent having the structure according to Formula I: (MCA-DA-)(PCA-DA)y-PCA-(DA-PCA)y(-DA-MCA) (I). In Formula I, at each occurrence PCA is independently a reacted polycarboxylate, at each occurrence MCA is independently a reacted monocaboxylate, at each occurrence DA is independently a reacted n-alkyl diamine, and y is 0 or a non-zero integer. Additionally, in Formula I, a weight-average molecular weight of the polyamide grease thickener is in a range of from about 450 g/mol to about 2600 g/mol. Additionally, in Formula I, the structure includes at least 4 amide bonds and at least two internal aromatic moieties are di-substituted in a para position.
