Abstract

Ethylene-octene copolymer (EOC) was cross-linked by dicumyl peroxide (DCP). Thermoplastic vulcanizate (TPV) based on polypropylene (PP)/EOC-DCP was prepared by dynamic vulcanization. Gel content was noted. Tensile creep properties of these samples at elevated temperatures (70- 200°C) were studied. Residual strain after 100% and 200% elongation were examined. EOC cross-linked with lower peroxide levels underwent creep failure easily at lower temperatures even with small loads. EOC with 0.6 wt. % of DCP was found to be the strongest even at higher temperatures and lower temperatures with heavier loads.
