FIELD: manufacturing technology.SUBSTANCE: invention relates to a method of producing porous material from a water-soluble polymer. Method is realized using a water-soluble polymer, such as a water-soluble polymer containing a hydroxyl group or an amide group, or an ether bond, or an amino group, or a carboxyl group. At which: solution is prepared, wherein the water-soluble polymer is dissolved in a mixed solvent from water mixed with a solvent, which is a carbonate, lactone, sulphonic, dinitrile or diketone compound, having a boiling point greater than the boiling point of water. Then the mixed solvent is removed from the solution, wherein the solubility of the water-soluble polymer in the solvent having a boiling point greater than the boiling point of water is lower than the solubility of the water-soluble polymer in water, and during evaporation and thereby removal of mixed solvent from solution a porous structure of water-soluble polymer is formed.EFFECT: technical result consists in development of simple and convenient method for production of porous material from water-soluble polymer.5 cl, 2 dwg, 1 tbl, 10 ex |
