PEO/CHCl3. Crystallinity of the Polymer and Vapor Pressure of the Solvent. Equilibrium and Nonequilibrium Phenomena

“…Furthermore such systems offer an opportunity to learn more about the occurrence of nonequilibrium phenomena in mixtures containing crystallizable components. The freezing in of intermediate states during the 16.04.03 approach of equilibria is well documented for polymer blends of semi-crystalline and amorphous components in general [1][2][3][4][5][6][7][8][9][10][11][12][13] and with PEO as one component in particular [14][15][16][17][18][19] . Analogous investigations for the considerably less viscous solutions of such polymers (which should therefore be less prone to non-equilibria phenomena) are to our knowledge lacking.…”
