Synthesis and characterization of a new liquid crystalline polymer - Butyryl chitosan

Abstract

Butyryl chitosan was synthesized and characterized by using FTIR, DSC, WAXD and PLM. Liquid crystallinity of butyryl chitosan was first reported in this paper. Comparing with chitosan, thermal stability and crystallinity of butyryl chitosan decreased but solubility increased, because hydrogen bond interactions between macromolecules were disrupted.
