Abstract: Effect of dicumyl peroxide (DCP) on the properties of ethylene-octene copolymer/polypropy-lene (POE/PP) blends was studied. It showed that crosslinking degree of POE increased, but elongation at break, tensile strength, and permanent deformation decreased with increasing content of DCP.Over loading of DCP may result in degradation of PP, and the melt flow rate increased. DSC showed that the degree of crystallinity of POE/PP decreased with increasing DCP loading. the influence of content of DCP on the phase structure was obvious. When the content of DCP was 1 phr, a fine dispersion of crosslinked POE in PP matrix was observed.
Key words: ethylene-octene copolymer, dicumyl peroxide, crystal morphology, phase morphology
