The capabilities of the dynamic quartz-resonator method
for determining the viscoelastic properties of liquids
in thin layers (to 1 m) have been studied. Aqueous solutions
of glycerin of different concentrations and motor oils of
different manufacturers have been used. The process of
polymerization of D-22 epoxy adhesive in the presence
of a hardener - polyethylene polyamine - has been
investigated as the model experiment. It has been shown
that the broadening of the resonant curve and the shift
of the resonant frequency plotted as functions of the
thickness of a liquid layer enable one to single out
the elastic and viscous components; this makes it possible
to judge the change in the structure of boundary layers
with processes that may occur at the interphase boundary.
