Phase behavior and ternary diagram construction for membrane forming polycarbonate solutions

Cloud points at different polymer concentrations were obtained by the simple titration method and compared with the numerically calculated theoretical binodal curves for Polycarbonate/Dimethylacetamide/Water (PC/DMAc/Water) and Polycarbonate/N-Methyl-2- pyrrolidone/Water (PC/NMP/Water). The interact...
