Abstract
The disclosed invention relates to a composition comprising a partially dehydrated product made by:(I) reacting (A) a hydrocarbyl substituted succinic acid or anhydride with (B) a polyol, a polyamine, a hydroxyamine, or a mixture of two or more thereof, to form a first intermediate product comprising: an ester, partial ester or mixture thereof when (B) is a polyol; an amide, imide, salt, amide/salt, partial amide or mixture of two or more thereof when (B) is a polyamine; or an ester, partial ester, amide, partial amide, amide/salt, imide, ester/salt, salt or a mixture of two or more thereof when (B) is a hydroxyamine, a mixture of a polyol and a polyamine, a mixture of a polyol and a hydroxyamine, a mixture of a polyamine and a hydroxyamine, or a mixture of a polyol, a polyamine and a hydroxyamine; the hydrocarbyl substituent of said acid or anhydride having an average of about 8 to about 200 carbon atoms; and(II) heating said first intermediate product at an effective temperature to form a second intermediate product with water of reaction being formed, and separating a portion of said water of reaction from said second intermediate product, when (A) is said succinic anhydride the…
