WebApr 14, 2024 · The extrusion temperature of 120–140°C was selected to match the T m of the copolymers, and the screw rotation rate of 35–55 rpm was selected to ensure viscosity was appropriate for the extrusion (Table 2). Higher rpm values led to a decrease in viscosity and difficulties in extrusion, as the polymer exhibited shear-thinning behavior.
