“…It is noteworthy to mention that even though tensile strength reduced slightly after incorporation of nanoclay, modulus is constantly increased. Similar findings were also obtained for polystyrene (Lee et al 2009) and polyurethane (Chung et al 2008) containing organoclay. It is clear from Fig.…”

“…As a result, the tendency of dispersed particles for aggregation decreased as the amount of PP-g-MA was increased. This finding is in agreement with the results reported in the literature [31,32]. The change in microstructure, due to improved adhesion at the interfacial region, would affect the macroscopic response of the material under the mechanical tests.…”

“…The addition of PP-g-MA resulted in an increase in yield stress, ultimate stress and elongation at break, as compared with those of uncompatibilized blend. The increase in yield stress and tensile strength with compatibilizer content originates from the interfacial activity of PP-g-MA, which by localization at the interface region enhances the interfacial interaction between the ABS particles and the matrix and, therefore, prevents the particles from early decohesion from the matrix under tensile tests [32]. The improved interfacial adhesion in the system not only gives rise to a finer dispersion of rubber particles in the matrix, but also causes an efficient stress transfer from the matrix to dispersed rubbery particles through the interfacial region.…”

Isotactic polypropylene (PP) modified by ABS and CaCO3 nanoparticles: effect of composition and compatibilization on the phase morphology, mechanical properties and fracture behavior

Attempt was made to improve the properties of isotactic polypropylene (iPP) by simultaneous incorporation of ABS and CaCO 3 nanoparticles. The goal was to achieve a balanced toughness and stiffness by the development of ternary PP/ ABS/CaCO 3 nanocomposite. The effects of compatibilization and composition on the phase morphology, mechanical properties and deformation behavior under impact loadings were systematically studied. The phase structure and mechanical properties of binary PP/ABS and PP/CaCO 3 systems was also investigated in detail to clarify the contribution of individual ABS and CaCO 3 components in the macroscopic response of ternary hybrid. It was found that the ABS could effectively toughen the PP matrix by the suitable compatibilization. Moreover, the CaCO 3 nanoparticles alone serve as stiffener and toughener in the material. Accordingly, the impact toughness of ternary PP/ABS/CaCO 3 nanocomposites was larger than those of compatibilized PP/ABS blend and PP/CaCO 3 system and, therefore, much higher than that of unmodified iPP. The mechanical properties and toughening mechanisms of different binary and ternary samples were rationalized by fractographic analysis. In the case of Izod impact-fractured samples, the characteristics of fractured surfaces were closely examined at the crack initiation and propagation stages of the impact fracture process.

“…On the other hand, ABS with a good impact resistance is one of the most popular toughening modifier. PP toughened with ABS in the presence of compatibilizer has been investigated in recent years . The studies of PP/ABS blends with multiwall carbon nanotubes (MWNT) which was reported by Khare, have displayed that dispersed type or morphology structure refined by MWNT.…”

“…From the studies by Patel et al, the use of PP‐ g ‐2‐hydroxyethyl methacrylate (2‐HEMA) improved the mechanical properties of PP/ABS blends. Hyung Gon Lee et al had examined mechanical, morphological and rheological properties of PP/ABS with PP‐ g ‐MAH. They reported that the compatibility of PP/ABS bends increased with the addition of PP‐ g ‐MAH.…”

The polypropylene-graft-cardanol (PP-g-cardanol) was prepared by reactive extrusion with polypropylene (PP) and natural renewable cardanol which could increase the interfacial energy of PP and inhibit the degradation of PP during the process of reactive extrusion and usage. In this article, PP-g-cardanol and polypropylene-graft-maleic anhydride (PP-g-MAH) were used as compatibilizers of the polypropylene (PP)/poly(acrylonitrile-butadiene-styrene) (ABS) blends. PP/ABS (70/30, wt %) blends with PP-g-cardanol and PP-g-MAH were prepared by a corotating twin-screw extruder. From the results of morphological studies, the droplet size of ABS was minimized to 1.93 and 2.01 lm when the content of PP-g-cardanol and PP-g-MAH up to 5 and 7 phr, respectively. The results of mechanical testing showed that the tensile strength, impact strength and flexural strength of PP/ABS (70/30) blends increase with the increasing of PP-g-cardanol content up to 5 phr. The complex viscosity of PP/ABS (70/30) blends with 5 phr PP-g-cardanol showed the highest value. Moreover, the change of impact strength and tensile strength of PP/ABS (70/30) blends were investigated by accelerated degradation testing. After 4 accelerated degradation cycles, the impact strength of the PP/ABS (70/30) blends with 5 phr PP-g-cardanol decrease less than 6%, but PP/ABS (70/30) blends with 5 phr PP-g-MAH and without compatibilizer decrease as much as 12% and 32%, respectively. The tensile strength of PP/ABS (70/30) blends has a similar tendency to that of impact strength. The above results indicated that PP-g-cardanol could be used as an impact modifier and a good compatibilizer, which also exhibited better stability performance during accelerated degradation testing.
