The present invention relates to new polymerisable fluorosurfactants. Commonly used surfactants are affected by phase out regulations or require tedious synthesis.


Fluoroorganics, particularly highly fluorinated monomers and surfactants, are widely used in a vast number of applications. These substances are well known for their excellent water and oil repellency, high gas solubility, as well as their unparalleled surfactant properties. Therefore, they are indispensable in omniphobic varnishes, firefighting foams, membranes, contact lenses, anti-fouling lacquers and in textile finishes. Unfortunately, most of these additives have risen ecotoxicological concerns. Moreover they are bioaccumultive and are consequently banned by governmental authorities worldwide. Alternatives often lack sufficient hydrophobicity or are not price-competitive. Our technology provides a phase out compliant alternative to currently used systems such as fluoroacrylates and related fluorosurfactants.


A new class of more environmentally-friendly polymerisable fluorosurfactants based on C6- or shorter perfluoroalkyl chains has been developed. The fluoro-surfactants consist of common salts or betaines. They contain, a polymerisable group, and a third task specific functional group. Via variation of the substitution patterns, different property profiles such as water solubility, feasibility of direct dyeing, or foaming behavior can be imposed.


  • Water contact angle >120° on textiles
  • Diiodomethane contact angle > 120° on textiles
  • Cost competitive alternative to fluoroacrylates
  • Easy access to fluorous crosslinkers
  • Water contact angle >140° on lacquers
  • Diiodomethane contact angles >140° on lacquers
  • Surface tension of water <25mN/m (0,5wt%)
  • Detachable fluorous ponytail at higher pH values
  • Reduction of (aqueous) waste process streams
  • Easy sequestration of fluorous anionicwater contaminats (e.g. PFOA) by derived fluorous polymers or (polymer) fluorosurfactant composites with Teflon, see figure 1)
