Abstract
The paper deals with the effect of mechanical treatment on chitin and chitosan isolated from Gammarus (Amphipoda) of Altay. Water-soluble carboxy-methyl ethers of chitin and chitosan in the solid phase were obtained using mechano-chemical activation in planetary centrifugal mill SPEX 8000. The obtained samples were characterized by means of IR spectroscopy, carboxy-methyl group content was determined, as well as molecular masses, solubility in water, relative viscosity of alkaline solutions.
