Abstract

Measurements of the complex permittivity were used to assess the amorphous phase miscibility in blends of poly(butylene terephthalate) (PBT) and several poly(ester-ether) (PEE) segmented block copolymers. In addition, complex plane parameters were determined for the component polymers and certain blends and their variation with hard segment content or blend composition is discussed. It was found that larger hard segment (tetramethylene terephthalate) content in the segmented block copolymers favors increased amorphous phase miscibility and cocrystallization. Thermal analysis and morphological evidence point to extensive cocrystallization in PEE-84/PBT mixtures.
