Chitin and chitosan with degree of deacetylation (DD) 57, 85, 89, and 90% were obtained as 250-μm microparticles. Their behavior with shear flow in aqueous and acidic solutions was studied. It was found that chitosan microparticles with various DD converted into gels as a result of swelling in water. Chitosan hydrogel particles with DD >85% were destroyed in shear flow without destroying the chains. The macromolecules were ordered in the direction of the flow.
