When we talk about a polymer being soluble in a particular solvent, we generally mean that the system lies between its LCST and UCST, that is, it forms a homogeneous solution over the entire composition range. Keep in mind, however, that homogeneous solutions can still be formed toward the extremes of the composition range below the UCST and above the LCST. [Pg.110]
