Cross-Linking of Ethylene-Octene Copolymer (EOC) by Dicumyl Peroxide (DCP)
Original language description
Ethylene-octene copolymer (EOC) was crosslinked 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) and by differential scanning calorimetry (DSC). From RPA data analysis real part modulus s', tan ?, and reaction rate were investigated as a function of peroxide content and temperature. The highest s'max and the lowest tan ? were found for 0.7% of DCP at 150°C. Chain scission was analyzed by slope analysis of conversion ratio, X in times after reaching the maximum. Less susceptible to chain scission are temperatures in range 150?170°C and peroxide levels 0.2?0.5%. Heat of reaction was analyzed by DSC at various heatingrates (5?40°C °C/min). It was found to be exothermic. By projection to zero heating rate, the reaction was found to start at 128°C with the maximum at 168°C.
