摘要：
This work presents results obtained for ternary blends of polypropylene (PP), a linear low density polyethylene (LLDPE) and two ethylene-propylene-norborene terpolymer (EPDM) of different viscosities. The effect of LLDPE added to the PP/elastomer blends is analyzed in terms of morphological features and impact properties. Press molded specimens were used throughout, this work. The LLDPE dispersive effect is verified independently of the elastomer viscosity. Ternary blends containing more than 50% EPDM in the disperse phase showed better impact strength than the corresponding binary PP/EPDM blend.
