The compatibilizing effect of the triblock copolymer poly(styrene-b-butadiene-b-styrene) (SBS) on the morphology and mechanical properties of immiscible polypropylene/polystyrene (PP/PS) blends were studied. Blends with three different weight ratios of PP and PS were prepared and three different con
## Abstract Blend systems of polystyrene‐__block__‐poly(ethylene‐co‐(ethylene‐propylene))‐__block__‐polystyrene (SEEPS) triblock copolymer with three types of hydrocarbon oil of different molecular weight were prepared. The __E__″ curves as a function of temperature exhibited two peaks; one peak at
Compatibilization of polystyrene/polypropylene (PS/PP) blends, by use of a series of butadiene-styrene block copolymers was studied by means of small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). The compatibilizers used differ in molar mass and the number of blocks. It w
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
