The isothermal crystallization behavior of blends of poly(ethylene terephthalate) and liquid crystalline polymers(LCP) was studied. The Avrami analyses were applied to obtain the information on the crystal growth geometry and factors controlling the rate of crystallization. The crystallization kinetics for the blends followed the classical Avrami equation up to a high degree of crystallization regardless of crystallization temperature, The values of Avrami exponent, n, for PET in the blends were estimated to be around 2, which indicate that the polymer crystals grow into one-dimensional linear or fiber-like crystallization mode. The crystallization rate, as expected, decreases with increasing the crystallization temperature.
