Described are fluorochemical surfactants derived from nonafluorobutanesulfonyl fluoride that contain polyalkyleneoxy side chains and may be copolymerized with acrylic acid or methacrylic acid to form polyacrylates or polymethacrylates. The surfactants surprisingly lower the surface tension of water and other liquids in the same or similar low values achieved by premier surfactants such as those derived from perfluorooctane sulfonyl fluoride.

São descritos os surfactants fluorochemical derivados do fluoreto do nonafluorobutanesulfonyl que contêm correntes laterais do polyalkyleneoxy e podem ser copolymerized com ácido acrílico ou ácido methacrylic para dar forma a polyacrylates ou a polymethacrylates. Os surfactants abaixam surprisingly a tensão de superfície da água e dos outros líquidos no mesmo ou os valores baixos similares conseguidos por surfactants do premier tais como aqueles derivados do fluoreto do sulfonyl do perfluorooctane.
