This work focuses on the effect of the unique molecular structure of OBC (olefin block copolymer) constituted by soft blocks and hard blocks on the compatibility of OBC/iPP (isotactic polypropylene) blends. Two OBCs with high and low octene content were selected to blend with iPP. The thermal behavi...
