Blends of Poly(Buty1ene Terephthalate) with Thermotropic Liquid Crystalline Polyesters. Morphology and Thermal Behavior

Abstract

Abstract Blends of poly(butylene terephthalate) with liquid crystalline poly (decamethylene 4, 4′-terephthaloyldioxydibenzoate) were studied in all the composition range by optical and electron microscopy and differential calorimetry. The morphology and phase transitions of the blends are markedly influenced by the composition and thermal history. The results suggest the occurrence of miscibility phenomena between the two components in the amorphous phase.
