Abstract
Poly (lauroyl) chitosans were prepared, by heterogeneous acylation, from samples of chitosan having varying degrees of deacetylation. The resultant changes in physical and chemical properties were discussed in the light of both infra-red and thermal analysis. It was found that the higher levels of free amine rendered the initial chitosan samples more susceptible to acylation at both the O and N positions, and this was explained in terms of the decrease in influence of inter- and intramolecular hydrogen bonding.
