Patent ID: 7595349

Claim:
A thermally cleavable surfactant composition, comprising: a Diels-Alder adduct; a group selected from the list consisting of anionic, cationic, and nonionic groups, wherein the anionic group is selected from the list consisting of carboxylic acid salts, amine salts, sulfonic acid salts, sulfosuccinate esters, sulfuric acid ester salts, sulfated polyethylenated alcohols, sulfated triglyceride oils, and phosphoric and polyphosphoric acid esters, the cationic group is selected from the list consisting of quaternary ammonium salts, amine salts, and amine oxides, and the nonionic group is selected from the list consisting of polyoxyethylenated alkyl phenols, alcohol ethoxylates, glycols, mercaptans, esters, alkanolamine, tertiary acetylenic glycols, pyrrolidones, alkylglycosides, and zwitterionic groups attached at a first end of said Diels-Alder adduct; and a non-polar alkyl group at a second end of attached to said Diels-Alder adduct distal to said first end.
