Miscibility and Properties of Liquid Crystalline P-Acetoxy Benzoic Acid Copolyester / Polybutylene Terephthalate Blends
Along with the development of new high-performance resins, new trends are being established in the processing of composites and polymer blends. However, the addition of rigid fillers into a polymeric matrix continues to have an adverse effect on the processability.1,2 To improve the mechanical properties of some polymers, generally inorganic fillers are compounded with the polymers. But the presence of solid fillers results in a dramatic increase in the melt viscosity. Thermotropic liquid crystalline polymers(LCP) have been studied because of then-inherent high stiffness and strength, high use temperature, excellent chemical resistance, low melt viscosity, and low coefficient of expansion. Because of these excellent properties, the blending of LCP with conventional polymers could result in materials that can be used as an alternative for short fiber reinforced thermoplastic composites; the in-situ composites have many potential advantages as compared with short fiber reinforced polymers3–9.
