Solid-phase modification of chitosan,pectin, and arabinogalactan with poorly soluble herbicide chlorsulfuron

The chemical modification of chitosan, pectin, and arabinogalactan with poorly soluble herbicide chlorsulfuron under mechanical effect is studied. It is shown that the mechanical stress on polysaccharides and herbicide provokes conformational and configurational transformations and disordering in biopolymer macromolecules as well as an increase in the concentration of defects in the crystalline phase of the polysaccharides and herbicide. The change in the conformational state of the polysaccharides under shock-shear impacts gives rise to intermolecular complexes stabilized by hydrogen bonds.
