Abstract

PEEK-PSU immiscible polymer blends were produced using a novel one-step high shear injection molding process without compatibilizers. A dual phase, co-continuous structure was predicted from melt rheology results and predicted to occur at a concentration ratio of 55/45 PEEK/PSU. PEEK and PSU were dry-blended at various compositions and processed with morphology, impact resistance, and tensile properties characterized. Morphology analysis shows good mixing at all concentrations and confirms a fine dual phase, co-continuous structure occurs at 55/45 wt. % PEEK/PSU. Additionally, the highest impact energy absorption occurs at dual phase, co-continuous concentration. Tensile properties increase with increasing PEEK concentration in PSU. At the 80/20 PEEK/PSU concentration, mechanical properties are comparative to neat PEEK, while proving more economically advantageous. Additionally, the lower viscosity of PSU, reduces processing pressures resulting in easier part fabrication of IMPBs, and enabling more complex geometries.
