Abstract: The molecular weight (Mw) of chitin was obtained by light scattering of glycolchitin andextrapolating of the plot of Mw vs deacetylation time. The values obtained were 3.18?106 and 3.75?106, respectively. The degradation of the polymer chain seems unavoidable during the preparation of chitinand glycolchitin as well as in the deacetylation, in spite of how mild the conditions were.

Key words: chitin, chitosan, glycolchitin, molecular weight
