The effect of talc content and shear rate at various temperatures on the coefficient of die swell during extrusion of filled polypropylene has been investigated. The experimental results served for the determination of empirical relationship which make it possible to calculate the die swell coefficient for any assumed filler content, shear rate and temperature.
