Viscosity and Prediction of Melt Flow Curves for Polycarbonate (PC) and Polyacrylonitrile butadiene styrene (ABS): PC/ABS (30/70) and PC/ABS (60/40 mass ratio)

Abstract

A study was conducted on a type of polymer blends based on polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) in the molten state under the influence of shear stresses, shear rate, and temperature. Through the aforementioned transformations, a technique of Prediction curves was performed to determine the possibility of knowing the displacement and structure of flow curves and viscosity along the shear axis and viscosity by selecting a specific reference value for the shear rate γ_{a (ref)}  and its ratio to the experimental shear rate γ_{a (T)}

Then, the slip coefficient α_T was determined, resulting in a main composition curve where the curves converge. This technique helps in determining the expected production conditions to be applied in various fields..
