Query: Formation of structure for gas-liquid, non-equilibrium polymer media   This paper examines the mechanisms of destruction and synthesis for
macromolecules, which may be propelled by external acoustic fields in the flows
of polymeric liquids containing a large number of gas bubbles. The dynamics of
these bubbles is assumed to govern by changing the flow geometry and exciting
sound oscillations in the flow. Mechanically-induced kinetic changes in
macromolecules (destruction and synthesis of polymer chains) will occur when
the bubbles collapse.
