Liquid crystal, phase transition, solution viscosity, cellulose ethers.Abstract
Application of a magnetic field is shown to be accompanied by an increase in the viscosity of hydroxyethyl cellulose, ethyl cellulose solutions and sodiumcarboxymethyl cellulose solutions in 2 - 4 times. The concentration dependences of solution viscosity in the presence of a magnetic field are described by curves with maxima.
