Polysaccharides like cellulose and chitosan are well known for their a
ptitude to generate thin films.-This paper reports the synthesis and c
haracterization of oxipropylated chitosan and their reaction with olig
oether-based mono and di-isocyanate. The resulting networks, containin
g LiN (CF3SO2)(2), were investigated by differential scanning calorime
try and complex impedance measurements (C) 1998 Published by Elsevier
