Cross-linking kinetics study and high temperature mechanical properties of ethylene-octene copolymer (EOC)/dicumylperoxide(DCP) system
Original language description
Ethylene?octene copolymer (EOC) was cross-linked by dicumyl peroxide (DCP) at various temperatures (150?200 °C). Six concentrations of DCP in range 0.2?0.7 wt.% were investigated. Cross-linking was studied by rubber process analyzer (RPA). From RPA dataanalysis real part modulus, tan(delta) and reaction rate constant K were investigated as a function of peroxide content and temperature. The highest max and the lowest tan(delta) were found for 0.7% of DCP at 150 °C. The quantitative analysis confirmed that the DCP?EOC cross-linking was occurring as first order reaction. The highest cross-linking kinetics constant K was found for 0.6% of peroxide at 200 °C. The activation energy of cross-linking EA obtained by Arrhenius plot had maximum at 0.5?0.6% of peroxide. While at 190?200 °C temperature range there was no detectable degradation for 0.2% of peroxide, for 0.4?0.7% of peroxide there was increasing level of degradation with increasing peroxide content. Generally, at low temperatures (
