摘要 |
This invention relates to a water-soluble, crosslinkable polymeric surfactant having fluorocarbon and ionic moieties. Such surfactant can be cured into tough, solvent resistant, low critical surface tension coatings useful for protective finishes on metal, plastics and fabrics. This surfactant has (1) at least one pendant fluorocarbon moiety and (2) at least one pendant ionic moiety which is capable of reacting with a counterion to form a crosslinked polymer. The reactive ionic moieties on the polymer chain can be anionic, cationic or zwitterionic (having an equivalent amount of both cationic and anionic moieties). |
