✦ Synopsis

The dynamic and tensile properties of Brabender mixed, compressionmolded miscible, and unreacted polyhydroxy ether of bisphenol A (Ph)/Hytrel blends were studied. Blending mainly produced a decrease in the specific volume, and in the strength of the ␤ transition of Ph. The ␤ transition strength decrease was attributed to both specific interactions and specific volume decrease. The measured modulus of elasticity, yield stress, and ductility of the blends were discussed as a result of the combined effect of the ␤ transition strength decrease, crystallinity, and free volume content changes, and the position of the T g s of the blends with respect to the testing temperature.
