Effects of temperature on nanocomposite extrudate swell

Author(s): Kejian Wang*, He Jianyun

Such processing variables as temperature and superposition of electromagnetic field can vary the molecular dynamics as reflected by the change in relaxation time. Thesematerial intrinsic propertieswere correlated with the extrudate swell ratio by one quantitative model, which was used to predict the variation in die swell due to temperature for phenophthalein poly (ether ether ketone), organobentonite-filled polypropylene nanocomposite and the variation in die swell due to superposed magnetic field for polystyrene melt. The good agreement of calculated values with experimental data illustrated this idea fitful for polymer melts and their composites.
