Abstract

The structure and properties of blends of ethylene-propylene-diene terpolymer(EPDM) and polyolefin blends have been investigated. The rheology and tensile properties of the EPDM/HDPE(high density polyethylene), EPDM/PP(polypropylene) binary and EPDM/PP/HDPE ternary blends were studied along with morphological analyses. Those properties were affected by preferential interaction of EPDM on HDPE, compared to that of EPDM on PP, for the binary blends. The preferetial interaction may stem from the molecular characteristics of EPDM to possess more ethylene units than propylene units in the elastomer. The EPDM played a role as compatibilizer for HDPE and PP in the EPDM/PP/HDPE ternary blends.
