Thermotropic main-chain liquid crystalline polymers have in themselves advantageous properties of low viscosity, die swell and thermal expansion and high modulus. Due to their expense and useful properties, they have mainly been blended with random coil thermoplastics. Blends of two liquid crystalline polymers have been much less studied, despite often showing synergistic properties of low viscosity and high modulus, even greater than either component. This poster will look at blends of LCPs with different copolymer constituents and copolymer ratios to determine which seem to result in miscibility in rigid rod mixtures. This will be done using relaxational techniques such as dielectric relaxation, dynamic mechanical analysis and the free volume technique, positron annihilation spectroscopy, which will be compared to density measurements.
