Abstract
Novel polymers are disclosed which can be used to prepare water-based compositions are disclosed having the capability of forming a uniform, low surface-energy, thin film on a substrate. Such compositions comprise a polymer having at least one fluoroaliphatic moiety and at least one anionic moiety, and a novel polymer having at least one fluoroaliphatic moiety and at least one oxazoline moiety.
Claims8
A water-based composition comprising an aqueous solution, emulsion, or dispersion of
- (a) a water-soluble or water-dispersible polymer or oligomer having at least one fluoroaliphatic moiety and at least one anionic moiety which is capable of reacting with an oxazoline or oxazine moiety, and
- (b) a water-soluble or water-dispersible polymer or oligomer having at least one fluoroaliphatic moiety and at least one oxazoline or oxazine moiety.
