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 amount of water of reaction that is separated is from about 0. 2 to about 0. 9 equivalents of said water of reaction per equivalent of said succinic anhydride, when (A) is said succinic acid the amount of water of reaction that is separated is from about 1.
