Abstract

Morphology and brittle temperatures of seven Polypropylene(PP)/Ethylene-Propylene rubber (EPR) blends were investigated. Sizes and interparticle distances for dispersed EPR particles were measured. EPR concentrations in PP matrix phases were also evaluated. Based on these results and brittle temperatures for the blends, molecular mechanism of brittleductile transition for PP/EPR blend was discussed.
