    • c is not expected. Evidence for this can be found in the shear response as measured with SANS, which shows no change in scattering intensity perpendicular to the flow direction. See refs 12, 13, and 27.

    • note
    • cγ + ̇ > 1, respectively. For a phase-separated critical mixture, there will be a relaxation time associated with thermal (zero-mean) fluctuations around an average, as in the one-phase region. There is also a characteristic relaxation time associated with the coarsening droplets themselves. Fluorescence microscopy studies of shear-induced mixing suggest that it is the latter that should be used in the reduced-variable description.

    • note
    • The scatter in the data is such that we do not attempt to resolve exact values of ν and A. Strictly speaking, the apparent critical exponents and amplitudes may be subject to a "Fisher Renormalization" upon dilution of a pure blend so that these quantities are not completely system independent. In eq 4, we use the approximate values 2ν ≈ 1, 1/3ν ≈ 1/2, and A ≈ 1/10.
