The emulsifying activity of a poly(hydrogenated butadiene‐b‐methyl methacrylate) (HPB‐b‐PMMA) copolymer is investigated in incompatible blends of a low density polyethylene and poly(styrene‐co‐acrylonitrile) resins (mainly ABS) prepared in the melt state on a two‐roll mill. Optical and scanning electron microscopy observations clearly demonstrate that a moderate amount of copolymer (5 wt %) very significantly decreases the particle size and enhances interfacial adhesion. The block copolymer is also responsible for a strong improvement in both the ductility and Charpy impact resistance of PE/ABS blends.
