Abstract
This paper presents the results of a study of the chemical structure a nd morphology of polyblends of chemically modified chitin and chitosan e with poly(ethylene oxide). Poly(ethylene oxide)(PEO) forms a compati ble one-phase blend with chitosane acetate salt (PEO/CHIACA) and a non -compatible two phase blend with dibutyrylchitin (PEO/DBCHI). The comp atible one-phase blend of PEO/CHIACA is formed due to the formation of strong hydrogen bonds between ether groups in PEO and hydroxy groups in CHIACA. Chemical and crystalline morphological structure is discuss ed here.
