The effect of compatibilizer on microfibrilar-phase formation in PE/PP blends

Abstract

The paper focuses on the role of ethylene-propylene-diene rubber compatibilizer in the formation of polypropylene microfibrils in polyethylene matrix during extrusion through semihyperbolic die. Several blends varying in phase composition was processed. The structure and properties were examined by scanning electron microscopy, DSC and tensile testing. Significant changes in morphology and properties were observed.
