critical temperature above which a mixture is miscible.
- Above the UCST and below the LCST, if it exists, a single phase exists for all compositions.
- The UCST depends upon the pressure and molar-mass distributions of the @C01281@ polymer(s).
- For a mixture containing or consisting of @M03667@ components, these may be different polymers or species of different molar mass of the same polymer.
