Fluorinated nonionic surfactants

摘要: The perfluoroalkylthio-substituted half esters and amides of succinic acid having the formula ##STR1## wherein R f is a perfluoroalkyl, 1 alkylene optionally interrupted with oxygen, sulfur or nitrogen atom, X oxygen NH, y zero 1, Q polyether polyester diradical moiety molecular weight 300 to 5000 polysiloxane 5 80 repeating units A hydrogen, hydroxyl, amino, alkoxy 21 carbons, phenoxy, alkylphenoxy 7 20 dialkylamino where each alkyl has 18 carbons group ##STR2## said compounds being prepared by first reacting maleic anhydride polyether, polyester, diamine derivative an alcohol primary amine then product perfluoroalkyl thiol. novel are useful as surfactants specific applications wetting agents in coatings, waxes, emulsions, paints resins.
