Rheological Properties of Liquid Crystalline Solutions of Cellulose Derivatives

The rheological properties and the liquid crystalline phase transitions of cellulose ethers solutions are studied. The concentration dependences of the enthalpy of the activation of a viscous flow are described by the curves with extremes (maxima and minima) caused by liquid crystalline transitions....

Description
Summary:The rheological properties and the liquid crystalline phase transitions of cellulose ethers solutions are studied. The concentration dependences of the enthalpy of the activation of a viscous flow are described by the curves with extremes (maxima and minima) caused by liquid crystalline transitions. These dependences are compared with the phase diagrams of studied systems.
