Abstract: ABSTRACTThis paper presents the results of transmission electron microscopy (TEM) studies on the distribution of polystyrene/polyisoprene/polystyrene (SIS) triblock copolymer compatibilizer in polystyrene-polyethylene homopolymer blends. The principal independent variable studied is the major-phase rheological properties (PSmajor/PEminor and PEmajor/PSmimor blends). The polyisoprene block was preferentially stained by OSO4 and could be clearly identified in cryo-ultramicrotomed TEM sections. The microstructura…
