“…Blending within the family of polyolefins has, however, been more common (Plochocki 1978). Although they are usually immiscible with each other, there exists some degree of mutual compatibility between them.…”

“…Phase segregation has been discussed in detail. 56 The tendency for segregation may be useful for those ultimate uses for which a PP layer or PP-rich layer may be advantageous, such as when the aging properties of PP would be an advantage. A number of recent patents and articles, however, suggest that in practice a minor proportion of ABS in PP may improve adhesion57 and ~l a t a b i l i t y~~ when the viscosity of the PP phase is increased by a filler such as talc.59 Presumably the ABS in both cases tends to be in the surface layers and to contribute the desired properties.…”

SynopsisA typical commerical polypropylene and acrylonitrile-butadiene-styrene terpolymer were coextruded and injection molded in various ratios and as the pure components. The rheological properties of the pure components in a single screw extruder were analyzed. Tensile and impact properties were compared with those of the pure polymers. Stress relaxation was analyzed by a simple three-element model. The data were related to the processing conditions. The morphology of the blends was inferred from extractive and staining tests on the blends.

“…Analysis of tensile data in terms of various theoretical models is low temperatures. 1 Incorporation of an elastomer, although increases the impact strength, results in presented to reveal the variation of interfacial adhesion and the stress concentration effect with blend deterioration of tensile properties. The mechanical properties of a thermoplastic elastomer blend can composition in both the unvulcanized and dynamically vulcanized blend systems.…”

Unvulcanized and dynamically vulcanized blends of isotactic polypropylene (PP) and butadiene styrene block copolymer (SBS) in the composition range of 10-40 wt % SBS were prepared by melt mixing in an internal mixer and evaluated for impact and tensile properties. Dynamic vulcanization of blends gave superior mechanical properties. Systematic changes with varying blend composition were found in stress-strain behavior in both the blend systems. The effect of blend composition on the state of dispersion and morphology of the dispersed phase droplets were studied by scanning electron microscopy. Analysis of the yield stress data in terms of various theoretical models revealed the variation of stress concentration effect with blend composition and higher interphase adhesion in dynamically vulcanized blends.
