CRITICAL BEHAVIOUR OF DYNAMIC TWIST VISCOSITY γ1 NEAR POLYCRITICAL POINTS
FRANCIS HARDOUIN, M. F. Achard, Gilles Sigaud · Le Journal de Physique Colloques · 1979
We report here the first measurements performed close to polycritical points revealed in binary mixtures of the dynamic twist viscosity γ1. Along the second order NSA line, drawn in a binary temperature-concentration diagram, critical behaviour is found to be the same. On the other hand, no divergence is observed near the "N-A-C" singular point.
