Control of phase separation behavior of PC/PMMA blends and their application to the gas separation membranes

Tailoring of phase‐segregation structures in two‐soft‐segment urethane/urea polymer membranes

“…The aforementioned observations are in accordance with the studies of Kim et al,17 who showed the relation between the gas‐permeation properties and morphology for blends of polycarbonate and poly(methyl methacrylate). The authors found that the permeability for miscible blends was lower than that for immiscible blends.…”

Miscibility of polysulfone blends with poly(1‐vinylpyrrolidone‐co‐styrene) copolymers and their interaction energies

“…To extract information about the interaction energy from the liquid–liquid phase boundaries shown in Figures 4 and 5, we assumed that to a good approximation these data corresponded to the spinodal curve. As reported elsewhere,23, 30 the morphology of the PSf/P(VP–S) blend observed with an image analyzer at the reported phase‐separation temperature could also be characterized by a high level of phase interconnectivity in both the minor and major phases caused by spinodal decomposition.…”

Miscibility of polycarbonates with copolymers containing cyclohexylmethacrylate

“…Interaction energies for the PC–CHMA, PC–MMA, and MMA–CHMA pairs (i.e., Δ P , Δ P , and Δ P ) were calculated from the phase boundaries of PC/P(MMA–CHMA) blends shown in Figure 1. The interaction energy of the PC–MMA pair, Δ P , calculated here was the same as that determined from the phase boundary of PC blends with PMMA, whose molecular weight was equal to 24,000 or less 7. The binary interaction energies involved in the DMPC/P(MMA–CHMA) (i.e., Δ P , Δ P , and Δ P ) were extracted from Figure 3.…”
