- Abstract
For the first time, polysaccharides: cellulose and xylan, isolated from birch wood by peroxide delignification in “acetic acid-water” medium in the presence of catalyst (NH4)6Mo7O24, were proposed to be used to obtain polymer composites (films). The initial components: cellulose, xylan, sodium alginate were characterized using the methods of FTIR, GC, GPC, laser diffraction and chemical analysis.It is shown that the introduction of ultrasound-activated birch bark cellulose into the composition of xylan-alginate composites leads to an increase in the strength of the films, an increase in their barrier properties with respect to water vapor, and also reduces the solubility of the films in water
