Abstract
In this work ternary polypropylene (PP) rich blends with ethylene propylene terpolymers (EPDM) and LLDPE are studied. Attention is focused on the effect of different viscosity ratios (β1/4 viscosity of dispersed phase/viscosity of PP matrix) on the particles sizes and particle size distribution of the dispersed phase. The incidence of the elastomer viscosity and dispersed phase content are also analyzed. A reduction in the viscosity ratio mainly affects the weight average particle diameter (Dw) rather than the number average particle diameter (Dn).
