Abstract

The blends of ethylene-propylene-diene terpolymer (EPDM) and high density polyethylene (HDPE) have been studied. Blends were prepared in a laboratory internal mixer, where EPDM was cured under shear with dicumyl peroxide (DCP) in the absence of HDPE and later blended with HDPE (cure-blend). The effect of DCP concentration, shear intensity of the mixing, and rubber/plastic composition were studied on the rheological, thermal and physical properties of the cure-blend. The results obtained were compared with those from blend-cure of Lee and Kim's work and discussed.
