Abstract

Dynamic mechanical, tensile and impact properties of polypropylene/ethylene-propylene-diene terpolymer (PP/EPDM) blends were investigated in the entire composition range. The composition dependence of the properties reflects the changes of the structure - determined earlier by direct morphological investigations - from a continuous PP phase through a transitional morphology to a continuous elastomer phase at high EPDM content. In the latter composition range, dispersed PP shows greater affinity towards block EPDM than towards statistical copolymer, which results in improved tensile failure properties and better structural stability of the block-copolymer-containing blends.
