Abstract
The critical concentration of lyotropic liquid crystalline phase transition
for chitin derivatives was determined using a polarization microscope. The
influence of molecular weight on critical concentration of liquid crystall
ine solution for chitin, chitosan, cyanoethyl chitosan and propionyl chitin
successively increases as the chain rigidity decreases. Therefore it can b
e used as an indicator of the chain rigidity.
