Abstract:
1. A method for making a thermally cleavable precursor surfactant compound, comprising the steps of: providing a maleimide compound comprising 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; mixing said maleimide compound with an alkylfuran compound and a solvent, to form a solution mixture; and heating said solution mixture to a first temperature for a first interval of time and reacting said maleimide compound with said alkylfuran compound; and cooling said solution mixture to room temperature.
