Abstract
Described are polymeric surfactants which include a fluorinated moiety and a non-fluorinated moiety where the fluorinated moiety contains two perfluoro-lower-alkyl sulfonamido segments in proximity to each other ; the surfactants provide more efficient and effective lowering of the surface tension of liquids and increase of wetting of a coating on a substrate surface.
