Diagram of phase separation

Figure 1. Schematic diagram of phase separation in a solution of PBT in MSA through the uptake of water from humid air The solution was suspended as eight droplets in a capillary (1.3 mm dia., 5 cm long) water diffused into the solution from the open end. Six distinct phases were observed, with the following characteristics ...

Fig. 11.4 Comparison in the theoretical phase diagrams of phase separation and polymer crystallization in polymer solutions, and the kinetic phase diagrams of crystal nucleation. The energy parameters are set as EpIEc =1.0 and BlEc = 0.076 for the labeled Cl curves, EpjE = 1.072 and BjEc = 0.03 for C2, and EpjEc = 1.275 and BjEc = —0.1 for C3. Three solution series share the same melting points (solid lines) at polymer concentration ( = 0.125, but different depths of critical points for phase separation. The dashed lines are binodals, and the dotted lines are spinodals. The data points are the onset temperatures for the uprising of crystallite numbers on isothermal crystallization. The straight lines are drawn to guide the eyes (Zha and Hu2007) (Reprinted with permission)...
