## Abstract Rheological studies of an experimental liquid crystalline (LC) copolyester were carried out using a capillary rheometer and a cone and plate rheometer. Rheological characteristics of the polymer in the nematic state were observed. The nematic melt was found to be pseudoplastic and the d
Melt rheological properties of blends of polypropylene (PP) and PP grafted with maleic anhydride (PP-g-MA) are studied using a capillary rheometer. A pseudoplastic flow behavior is observed. The pseudoplasticity of the melt reduces with an increase of PP-g-MA content and/or temperature. The PP-g-MA
