摘要：

The shear flow of liquid-crystalline solutions of (hydroxypropyl)cellulose in water and poly (γ-benzyl L-glutamate) in m-cresol has been investigated by small-angle light-scattering techniques. A comparison between the rheological and rheooptical properties shows that the physical mechanisms involved under the shear flow undergo a drastic modification at the onset of the shear thinning region at high shear rates. A new structural model, based on the defects concept, is proposed for the rheology of lyotropic polymers. © 1990, American Chemical Society. All rights reserved.
