A poly­(ethylene-cb-propylene) comb block copolymer (P­(E-cb-P)), prepared by copolymerization of vinyl-terminated atactic polypropylene and ethylene, was used to compatibilize immiscible blends of high-density polyethylene (HDPE) and isotactic polypropylene (iPP). Addition of 5 wt % P­(E-cb-P) resu...
