SynopsisThis article presents study of melt rheological properties of composites of polypropylene ( z-PP) filled with wood flour (WF), at filler concentrations of 3-20 wt%. Results illustrate the effects of (i) filler concentration and (ii) shear stress or shear rates on melt viscosity and melt elasticity properties of the composites. Incorporation of WF into z-PP results in an increase of its melt viscosity and a decrease of melt elasticity such as die swell and first normal stress differences; these properties, however, depend on filler concentration. Processing temperature of the filled i-PP increases as compared to the nonfilled polymer.

“…Maleic anhydride grafted ABS has been used as impact modifier for polycarbonate/ABS blends. [16][17][18][19][20][21][22] Previously, we investigated the effects of maleic anhydride-grafted polypropylene (PP-g-MAH) and maleic anhydride-grafted poly(styreneco-acrylonitrile) (PP-g-SAN) on the mechanical, morphological, and rheological properties of a PP/ABS blend. PP is one of the most widely used commodity polymers.…”

“…PP/ABS blends have been investigated in recent years and several papers describe PP/ABS blending. [16][17][18][19][20][21][22] Previously, we investigated the effects of maleic anhydride-grafted polypropylene (PP-g-MAH) and maleic anhydride-grafted poly(styreneco-acrylonitrile) (PP-g-SAN) on the mechanical, morphological, and rheological properties of a PP/ABS blend. 16,17 Markin and Williams 18 examined mechanical properties and morphology of a PP/ABS blend and reported improved impact strength with the addition of dispersed ABS to a PP matrix.…”

The effects of maleic anhydride-grafted styrene-ethylene-butylene-styrene copolymer (SEBS-g-MAH) on the mechanical and morphological properties of polypropylene (PP) and poly(acrylonitrile-butadiene-styrene) (ABS) blends were investigated. Based on mechanical properties, including impact and tensile strengths, the PP/ABS (70/30) blends containing SEBS-g-MAH showed improved impact strength with minimal loss of tensile strength. As determined from morphological studies of the PP/ABS blends, addition of SEBS-g-MAH decreased PP/ABS blend droplet size more than the addition of SEBS. Additionally, the effects of SEBS-g-MAH and SEBS on the mechanical and morphological properties of the PP/ABS (70/30) blends were investigated during accelerated aging in an oven at 90 C for 72 h (one cycle). The impact strength of the PP/ABS (70/30) blends with SEBS-g-MAH (7 phr) decreased less than 10% after five cycles, but blends with SEBS (7 phr) and blends without compatibilizer decreased as much as 37%. The tensile strengths of the PP/ABS (70/30) blends after accelerated aging indicated a trend similar to that of the impact strength. The morphological studies indicated no significant changes in the PP/ABS (70/30) blends with SEBS-g-MAH; however, many cavities and damages were observed in the blend with SEBS. The above results suggest that SEBS-g-MAH acts as an impact modifier and as a good compatibilizer in the PP/ABS (70/30) blends.

“…In order to improve the ductile properties of the PP, ABS which is one of the most widely used rubber-toughened polymers could be used with a compatibilizer because of its poor compatibility between PP and ABS. [38][39][40][41] For the PP/ABS blends, Patal et al have used compatibilizer such as acrylic acid grafted PP and hydroxyethyl methacrylate grafted PP. 40 From the study of Kum et al, poly(styrene-co-acrylonitrile) grafted PP (PP-g-SAN) was used as a compatibilizer in the PP/ABS blends, in order to improve the compatibility of the PP/ABS blends.…”

Effects of PP-g-MAH on the Mechanical, morphological and rheological properties of polypropylene and poly(acrylonitrile-butadiene-styrene) blends

The effects of maleic anhydride-grafted polypropylene (PP-g-MAH) addition on polypropylene (PP) and poly(acrylonitrile-butadiene-styrene) (ABS) blends were studied. Blends of PP/ABS (70/30, wt%) with PP-g-MAH were prepared by a twin-screw extruder. From the results of mechanical testing, the impact, tensile and flexural strengths of the blends were maximized at a PP-g-MAH content 3 phr. The increased mechanical strength of the blends with the PP-g-MAH addition was attributed to the compatibilizing effect of the PP and ABS blends. In the morphological studies, the droplet size of ABS was minimized (6.6 μm) at a PP-g-MAH content of 3 phr. From the rheological examination, the complex viscosity was maximized at a PP-g-MAH content of 3 phr. These mechanical, morphological and rheological results indicated that the compatibility of the PP/ABS (70/30) blends is increased with PP-g-MAH addition to an optimum blend at a PP-g-MAH content of 3 phr.
