Influence of structure on phase behavior of polyamide blends

Phase phenomena of blends of several aromatic polyamides in a comprehensive series of aliphatic polyamides and copolyamides are studied. The predictive ability of a binary interaction model to correlate experimental observations with fundamental chemical constitution has been addressed. The model provides a good description of experimental behavior. By incorporating these new observations into the model, additional boundary conditions have been estimated to provide semiquantitative corrections such that agreement between theory and experiment is improved
