La. Nudga et al., RHEOLOGICAL PROPERTIES AND SUPERMOLECULAR ORGANIZATION OF MODERATELY CONCENTRATED-SOLUTIONS OF CHITOSAN IN ACETIC-ACID AS A FUNCTION OF PH, Russian journal of applied chemistry, 66(1), 1993, pp. 166-169
We have studied the rheological properties of moderately concentrated
solutions of chitosan in 2% acetic acid at different pH values. We hav
e investigated the supermolecular organization of these solutions by p
olarized-light scattering. We have demonstrated the existence of assoc
iative formations of a fluctuational nature. We have observed microani
sotropic order in the associates of macromolecules. We have observed a
correlation between the characteristics of the supermolecular structu
re of the chitosan solutions and the conformational characteristics of
isolated macromolecules.
