Abstract
Cellulose acetate butyrate (CAB) fibers were prepared by spinning from liquid crystalline (LC) solutions containing lithium chloride (LiCl). Ionic interactions were observed between carbonyl oxygen and lithium cation by C-13 nuclear magnetic resonance (NMR) spectroscopy. Isotropi zation of the anisotropic phase by LiCl was found to cause a dramatic rise in the viscosity of LC solutions. The mechanosorptive creep behav ior described earlier decreased in the presence of residual LiCl salt, possibly due to the formation of electrostatic interactions between L i+ and CAB backbone.
