Abstract
Lactone oxazoline reaction products of hydrocarbon substituted lactone carboxylic acids, for example, polybutyl lactone carboxylic acid, with 2,2-disubstituted-2-amino-1-alkanols, such as tris-(hydroxymethyl)aminomethane (THAM), and their derivatives are useful additives in oleaginous compositions, such as sludge dispersants for lubricating oil, or anti-rust agents for gasoline.
