Abstract
The butyrylation of chitosan of various degrees of acetylation yielded derivatives soluble in water and methanol. Solutions of the derivatives in these solvents when evaporated afforded tough clear flexible films. The effect of the degree of butyrylation on a range of deacetylated chitins was investigated and the resulting derivatives characterized by infra-red absorption spectroscopy and differential scanning calorimetry.
