Patent

CA 2592289

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.

L'invention concerne des tensioactifs polymères qui comprennent une fraction fluorée et une autre non fluorée, la première contenant deux segments perfluoro-alkyle inférieure-sulfonamido proches l'un de l'autre. Ces produits réduisent plus efficacement la tension superficielle des liquides et augmentent le mouillage d'un revêtement sur une surface de substrat.
