The influence of processing temperature on the morphological and mechanical properties of polycarbonate (PC) blended with a thermotropic liquid crystalline polymer (TLCP) has been studied. At a barrel temperature of 310 degrees C, the TLCP of the blends exhibits the high orientation level and fiber alignment which correspond to maximum tensile strength. This indicates that the processing temperature might result in the change of the viscosity ratios of the dispersed and continuous phase and is one of the main processing parameters.
