High-density polyethylene/cycloolefin copolymer (HDPE/COC) blends were prepared using an optimized process resulting in fibrous morphology of COC. Based on rheological data and theoretical predictions, the research was focused on three HDPE’s with high viscosity and on the HDPE/COC compositions with 20, 30 and 40 wt.% of COC. A significant increase in both macromechanical and micromechanical properties of softer HDPE matrix due to tougher oriented COC fibres was achieved in all cases. Combined results from scanning electron microscopy, tensile testing, microhardness measurements and theoretical calculations based on Equivalent Box Model (EBM) showed that the interfacial adhesion is unusually high and indicated partial miscibility of the components.
