Elastic properties of polypropylene/ethylene-octene copolymer blends
Original language description
Blends of polypropylene (PP) and ethylene-octene copolymer (EOC) across the whole composition range (10, 20, ., 80, 90 wt.%) were investigated with focus on mechanical properties. Samples (0-50% of PP) were stretched in a tensile machine to given elongations (100, 200 and 300%) and then the crosshead returned to the initial position. The residual strain values were obtained from the hysteresis curves. These residual strain values were plotted as a function of applied strain and PP content. Stress at given elongation (M100 and M300) was also plotted as a function of PP content. At low PP content (0?20%), residual strain and stress at given elongation are close to those of pure EOC. A steeper increase in these values was observed for concentrations 20?50% of PP. Another set of experiments involved tensile testing to break (full range of concentrations). From these experiments, tensile modulus and stress at break were evaluated and plotted as a function of PP content. Modulus values were
