Patent ID: 7361629

Claim:
An oil-soluble composition comprising a compound selected from the group consisting of bis-succinimide-di-amide-amines of the structure: wherein PIB is polyisobutylene, x is an integer from 1 to 6, y is an integer from 1 to 10, R 2 is selected from the group consisting of —NH 2 , —NH(CH 2 ) n ) m NH 2 , —CH 2 —(CH 2 CH 2 ) n — NH 2 , and -aryl-NH 2 , in which n and m have a value of from 1 to 10, and R 3 is selected from the group consisting of —H, alkyl, alkenyl, alkoxy, arylalkyl, and alkaryl having 4 to 24 carbon atoms and with the proviso that only one of R 2 and R 3 has a terminal NH 2 group; bis-succinimides containing an imide-amine substituted olefin of the structure: wherein PIB, x, y, R 2 , and R 3 are as defined above and bis-succinimide-amides containing an imide-amine substituted olefin of the structure: wherein PIB, x, y, R 2 , and R 3 are as defined above, and R 7 is selected from the group consisting of H, amine salt, and a metal salt.
