Hydration in aqueous polymer solutions and closed-loop miscibility gaps

4 Hydration in aqueous polymer solutions and closed-loop miscibility gaps 

Phase diagram of the hydrated polymer solutions. The number n of repeat units is varied from curve to curve. Binodals (solid lines) and spinodals (broken hnes) are drawn. The critical solution points are indicated by the open circles, (a) Xq = 0.002, (b) Xq = 0.003, (c) Xp=0.005. (Reprinted with permission from Ref. [29].) 

9 (a) Hypercritical point where a miscibility loop shrinks to a point (n = 37). (b) Double critical 

11 (a) Shultz plot of PEO. UCST (dotted lines) and LCST (solid lines) of homopolymer PEO
