Abstract
Adequate dispersion of the additive in polymer composites is vital to their performance. Dispersion occurs via rupture, erosion and collision induced mechanisms. Organophosphorus salt/PET nanocomposites were manufactured on a co-rotating fully intermeshing pilot scale twin screw extruder to determine the impact of operating conditions on the mixing achieved in order to understand the level of control available over the process. The effect on key dispersion mechanisms is discussed. Dispersion was found to increase with decreasing throughput, increasing screw speed and increasing molecular weight of the polymer. Linear relationships between calculated parameters including specific mechanical energy, degree of fill and specific throughput were also observed. A need for a compromise between achieving the desired level of mixing and maintaining the molecular weight of the polymer is established.
