摘要：
The phase transitions and rheological properties of the hydroxyethyl cellulose-water, hydroxyethyl cellulose-DMAA, hydroxyethyl cellulose-DMF, hydroxypropyl cellulose-water, hydroxypropyl cellulose-DMF and ethyl cellulose-DMAA systems were studied. The regions of existence of the isotropic and anisotropic phases were determined. Application of a magnetic field is shown to be accompanied by a change in the relative viscosity by a factor of 1.3-4. The concentration dependences of viscosity in the presence of a magnetic field are described by curves with an extremum. (C) 2014 Elsevier Ltd. All rights reserved.
