Abstract

Two ethylene-octene copolymers (EOC - with octene wt.% of 20 and 35) were crosslinked using dicumyl peroxide (DCP). Crosslinking studies were done using rubber process analyzer (RPA) at 150-200 °C range. Highest s'max (maximum elastic torque) was found for EOC-20 with low octene content, always. High-octene EOC underwent more degradation. From dynamic mechanical analysis (DMA), storage modulus (M') and glass transition temperature (Tg) were found decreasing with increasing octene content. Differential scanning calorimetry (DSC) revealed the inverse effect of octene content on crystallinity and melting point. For high-octene EOC, increased β-scission has resulted in the poorer crosslinking and inferior properties.
