Stress-induced phase transitions in polydimethylsiloxane-methyl ethyl ketone system

Stress-induced phase transitions in polydimethylsiloxane-methyl ethyl ketone system with the upper critical solution temperature were studied. The inversion of the effect of shear rate on phase transitions was discovered; the miscibility of components increases at low shear rates and decreases at high shear rates. The shear field qualitatively changes the pattern of boundary curves; this suggest that the mechanism of phase separation in solutions changes.
