Polymeric polyol ester additives for metal working applications are described that have lower pour points and improved solubility in API Group II and III basestocks. The polyol esters are made from tri and/or tetrahydric alcohols, a linear fatty monocarboxylic acid, a short dioic acid, and a alk(en)yl substituted succinic acid or its anhydride.
La présente invention a trait à des additifs d'esters de polyol polymériques pour des applications de travail de métaux présentant une point d'écoulement plus faible et une solubilité améliorée dans des huiles de base API de Groupe II et III. Les esters de polyol sont produits à partie d'alcools tri- et/ou de tétrahydriques, d'un acide monocarboxylique gras linéaire, d'un acide dioïque court, et d'un acide substitué d'alk(én)yle ou son anhydride.
