Effect of interface mobility on coalescence of the dispersed phase domains upon processing of 20/80 EPDM/PP melt blends

The effect of crosslink density (Nc) of the inner EPDM rubber phase on the coalescence of its domains during capillary extrusion of 20/80 EPDM/PP blends has been studied. The EPDM phase was preliminary loaded with varying amounts of vulcanization agents followed by the reactive blending with PP matr...

description The effect of crosslink density (Nc) of the inner EPDM rubber phase on the coalescence of its domains during capillary extrusion of 20/80 EPDM/PP blends has been studied. The EPDM phase was preliminary loaded with varying amounts of vulcanization agents followed by the reactive blending with PP matrix on a roll mill at 185 o C. The samples were extruded through a capillary rheometer at 185 o C. It is demonstrated that even at low shear rate the convergent flow results in strong coalescence efficacy of droplets in raw blends and in complete suppression of coalescence at low Nc.
