ABSTRACT:
This invention relates to compositions which are useful as additives in lubricants and fuels, and more particularly, to additives which are chlorine-free or contain only minor amounts of chlorine. More particularly, carboxylic compositions are described which are prepared by reacting a terpolymer derived from a mixture of monomers comprising ethylene, an alpha-olefin containing 3 to about 20 carbon atoms, and a non-conjugated polyene with an alpha,beta-monounsaturated dicarboxylic acid or reactive derivative thereof. These carboxylic compositions may be used in lubricating oil or fuel compositions or may be used to form carboxylic derivative compositions which are useful in lubricating oil and fuel compositions. Such useful carboxylic derivative compositions can be prepared by reacting at least one of the above-described carboxylic compositions with a reactant selected from the group consisting of (A) amines characterized by the presence within their structure of at least one H--N< group, (B) alcohols, (C) reactive metal or reactive metal compounds, and (D) a combination of two or more of any one of (A) through (C), the components of (D) being reacted with one or more of the carboxylic compositions simultaneously or sequentially in any order. In another embodiment, the carboxylic composition may be prepared by reacting a mixture of an alpha-olefin polymer, the above-described terpolymer, and an alpha,beta-monounsaturated dicarboxylic acid or reactive derivative thereof.
