OF A DISPERSED MAGNETIC SUBLAYER

A magnetooptical method of measurement of viscosity, which 
is based on recording the optical response (induced by the magnetic-field 
pulses) of a two-layer system resulting from the sedimentation of 
ferroparticles dispersed in the liquid under study, has been proposed. 
The procedure has been described and the results of measurement of 
the rheokinetics of a number of media, including polymer compositions 
formed into a thin film, in heating, evaporation, and polymerization 
have been presented.
