Abstract
The invention discloses a preparation method of a fluorine-containing polysaccharide high-molecular compound, which comprises the following step of: reacting a polysaccharide high-molecular compound with fluorosulfonyl picolinic acid for at least 30 minutes in a solvent in an alkaline environment at 0-80 DEG C to obtain the fluorine-containing polysaccharide high-molecular compound. The polysaccharide high-molecular compound is water-soluble, and each structural unit contains at least two hydroxyl groups. According to the fluorine-containing polysaccharide high-molecular compound and the preparation method thereof, fluorine atoms are introduced into the polysaccharide high-molecular compound, so that the physical and chemical properties are improved.
