EnglishA monodispersed green masterbatch was produced through an industrial extrusion process, by mixing a commer-cial Polyamide 6 matrix (PA6) with a halogenated copper phthalocyanine green pigment. The production process was investigatedand optimized in order to improve the pigment dispersion, reducing the clogging power and increasing the color strength of theresulting products. The compounding process based on three extrusions without filtration led to a filter pressure value (FPV)reduction of about 84% and a relative color strength (RCS) increase of about 50% with respect to the standard production process(i.e single extrusion). The thermal stability of the prepared compounds was evaluated by rheological test, viscosity measurements,and end group analysis, and it was found that a triple extrusion without filtration promoted thermo-oxidative matrix degradation.However, the same processing conditions led to a significant reduction of the production waste, increasing the productivity andthe quality of the final product. © Wiley Periodicals, Inc.
