Influence of branching density on the cross-linkability of ethylene-octene copolymers

Original language description

Ethylene-octene copolymers (EOCs) with two different octene contents (20 and 35 wt%) and the same melt flow index (3 g per 10 min) were cross-linked using various levels (0.3, 0.5 and 0.7 wt%) of dicumyl peroxide at different temperatures. Cross-linkingand degradation were analyzed by rubber process analyzer (RPA) within a temperature range of 150-200 °C. The highest s max (maximum elastic torque) and the lowest tan(delta) were found for EOC-20 with low-octene content at all cross-linking temperatures.Lower peroxide efficiency was observed in the case of the high-octene copolymer. Increased degradation was observed with increasing cross-linking temperature. High-octene EOC was found to be more vulnerable to degradation. According to dynamic mechanical analysis, the storage modulus (M´) and the glass transition temperature (T g) obtained from the tan(delta) peaks were found to decrease with increasing octene content. The differential scanning calorimetry (DSC) results show that the oc
