| titleOfInvention | Fluorine-containing polyacid monomer and preparation method thereof, polyamide and preparation method thereof, and polyamide film |
| abstract | The invention provides a fluorine-containing polyacid monomer and a preparation method thereof, polyamide and a preparation method thereof, and a polyamide film, and belongs to the technical field of organic synthesis. The fluorine-containing polyacid monomer provided by the invention has a spiro microporous structure, a flexible group and a large-volume trifluoromethyl structure, and the polyamide synthesized by using the fluorine-containing polyacid monomer has a microporous structure and a hyperbranched structure, so that the gas permeability of the polyamide is good; the existence of ether bond increases the free volume and flexibility of a polymer molecular chain, so that the solubility of polyamide is good; the polyamide membrane prepared by the polyamide of the invention has better gas selectivity and permeability. The invention provides a preparation method of the fluorine-containing polyacid monomer and the polyamide, which is simple and feasible, has short synthetic route and is suitable for industrial mass production. |
