Amorphous polyurethane—polyether blends

Abstract As we have reported recently, the application of association models has provided a theoretical basis for the calculation of the free energy changes and phase diagrams of binary polymer blends in which hydrogen bonding plays a significant role. Here we perform theoretical calculations of the phase diagrams of a number of amorphous polyurethane—polyether blends. The concordance between the theoretical predictions and gross experimental observations of the miscibility of these polymer blend systems is very encouraging.
