Blends of polyethylene terephthalate (PET) and polypropylene (PP) at compositions 20/80 and 80/20 were modified with three different styrene-ethylene/butylene-styrene (SEBS) triblock copolymers with the aim of improving the compatibility and in particular the toughness of the blends. The compatibili
## Abstract Nanocomposites of nanosized CaCO~3~/polypropylene–ethylene copolymer (PPE) and nanosized CaCO~3~/PPE/styrene–butadiene–styrene (SBS) were prepared by using a two‐roll mill and a single‐screw extruder. By adding CaCO~3~ nanoparticles into the PPE matrix, the toughness of the matrix subst
## Abstract **Summary:** Polystyrene (PS) was toughened with ethylene‐propylene‐diene terpolymer (EPDM) in the presence of styrene‐butadiene‐styrene block copolymer (SBS). Incorporation of SBS into the PS/EPDM blends clearly improved the impact properties. For PS/EPDM/SBS (mass ratio: 69/21/10) ble
