The focus on visual evidence of morphological forms of filled polymer blends emerged in the literature in conjunction with studies on electron microscopy. Breuer et al. [28] used a series of SEM images to study morphology development in CB-filled linear low density polyethylene (LLDPE)/high impact polystyrene (HIPS) blends. These authors made the following observations. First, CB particles were observed to be localized in LLDPE droplets. Second, the presence of CB particles reduced the size...

Both component polymers form separate, but intermingled phases (Figure 1). Since polystyrene and polyethylene are immiscible, simple compounding gives very brittle products. Addition of a compatibilizer (e.g., RCM1 or RCM 2) makes it possible to obtain useful blends. Morphology of polystyrene/polybutadiene blends can be seen from Figures 5 and 6 in Polystyrol description.

Studies on the morphology and on the melt rheological, tensile, and impact properties were carried out on ternary blend of iPP with two of the following polymers low and high density polyethylene, styrene-b-ethylene butylene-b-styrene triblock copolymer, polystyrene, and acrylonitrile-butadiene-styrene terpolymer (30-33). The results are interpreted for the effect of each individual component by comparing the ternary blends with the respective iPP-based binary blends as the reference systems. 

In situ polymerization to prepare immiscible blends was pioneered by Watkins and McCarthy [108], stimulating other researchers to apply this methodology to prepare novel polymer blends [109-112], fiber-reinforced composite materials[39], and electrically conducting composites [66, 67, 113-116]. Polymer blends produced in this manner include polystyrene/poly(vinyl chloride) [117, 118], polysty-rene/PET [119], nanometer-dispersed polypropylene/polystyrene interpenetrating networks [120], polypropylene/polystyrene [121] and polyethylene/polystyrene [122]. The resultant polymer blend may have a unique morphology compared to the traditionally prepared counterpart (if it is feasible to prepare such a blend via conventional procedures) and therefore demands a thorough investigation.
