Abstract
The processes of solid-phase deacetylation of chitin and preparation of chi tosan-cellulose compositions were combined under conditions of shear deform ation in the presence of a crosslinking agent, diglycidyl ether of oligo(et hylene oxide). The resulting products were investigated by potentiometric t itration, elemental analysis, and IR spectroscopy. It is established that t he presence of cellulose in the reaction mixture favors an increase in both the system homogeneity and the degree of chitin deacetylation.
