    • Muthukumar and co-workers also applied the Fredrickson-Helfand approach to their mean-field density functional theory for block copolymers for all segregation levels to include fluctuations effects. Later, they developed a fluctuation theory for the ternary blends of diblock copolymers and two homopolymers using the same one-loop approximation with the Ohta-Kawasaki-type parametrized function for the second-order correlation function to predict the destruction of the mean-field Lifshitz critical point.

    • We have shown that an incompressible block copolymer system with such specific interactions can exhibit not only the LDOT, but also a loop with both LDOT and UODT. See J. Cho, Y. K. Kwon, J. Polym. Sci., Part B: Polym. Phys. 41, 1889 (2003). Meanwhile, the diblock copolymer of polystyrene and poly(n-pentyl methacrylate), which was measured by Kim and co-workers (Refs. 9 and 10) indeed revealed such an immiscibility loop.

    • The near-symmetric blend of partially deuterated PEE and PDMS having the degree of polymerization of 30.5 and 29.2, respectively, revealed the cloud point of 417 K (Ref. 24). The experimental binodals, measured by Roe and Zin for the blends of PS and PBD with the molecular weights of 3500 and 2660, respectively, exhibit the upper critical solution temperature of ~495 K. See R. J. Roe and W. C. Zin, Macromolecules 13, 1221 (1980).

    • It was also found by Schwahn and co-workers that the mean-field spinodal point for the near-symmetric diblock copolymer of MW= ∼ 15 700 from PS and deuterated PBD was increased by ∼ 12 K upon pressurization up to 200 MPa. However, the order-disorder transition for this system did not show apparent changes with pressure. See H. Frielinghaus, B. Abbas, D. Schwahn, and L. Willner, Europhys. Lett. 44, 606 (1998).
