Abstract
The present invention relates to a fluorine-containing amphoteric polymer for surface coating and preparation method thereof, in particular, to a fluorine-containing amphoteric polymer for surface coating and preparation method thereof in which a hydrocarbon compound with hydrophilic groups serves as a main chain and a macromonomer prepared by copolymerization of an unsaturated hydrocarbon compound and a perfluoro alkyl compound is incorporated into side chains, thereby imparting amphoteric property on the present polymer. Therefore, the present polymer allows self-emulsification and shows soil release, water-repellent and oil-repellent properties with no help of emulsifier, applicable to a variety of industrial fields such as coating, adhesive, fiber, precision chemistry, biological/biochemical industry, electric/electronic, automobile and metal industries.
