“…The presence of two peaks in the blends confirms the immiscibility between the phases. However, there are only one transition temperature was observed for PBT/SEBS-G-MAH blend in the test temperature range [2,8,9,24]. The results confirm that there are well miscibility between PBT and SEBS-G-MAH and immiscibility between PBT and SEBS.…”

“…Poly (butylene terephthlate) (PBT) is an important engineering thermoplastic with many valuable properties [8][9][10][11]. These characteristics make it very useful for manufacturing injection-molded articles for domestic, electrical, and automotive applications where the above mentioned characteristics are required [12].…”

“…The un-notched impact strength of PBT is high, however, it is strongly notch sensitive and gives brittle fracture [13][14][15]. It is necessary to modify PBT with other polymers and toughening modifiers to overcome its brittle behavior for diverse applications [9,[16][17][18].…”

Abstract.A series of poly (butylene terephthlate) (PBT)/ styrene-ethylene/butylene-styrene (SEBS) and PBT/ (styreneethylene/butylene-styrene)-G-(Maleic anhydride) (SEBS-G-MAH) blends were prepared by melt blending method. And the morphology, mechanical properties were studied to identify the effect of SEBS or SEBS-G-MAH weight fraction on the properties of blends. SEM show that the minor phase was hardly distinguishable in the blend of PBT/SEBS-G-MAH as the result of the improvement in dispersibility, compared with PBT/SEBS blends. These results lead to the different mechanical properties between PBT/SEBS and PBT/SEBS-G-MAH blends.

“…22,23 This has been attributed to the interference of the dispersed phase to the matrix's polymer chain mobility through imposition of physical barrier. However, incorporation of EVA copolymer into i-PP enhanced the crystallinity of the latter, and the crystallinity increases with the concentration of EVA copolymer as shown by the DSC measurements given in Table I.…”

Polymer blend technology has been widely used for the past several years for the modification or enhancement of mechanical properties of polymers to obtain an overall balance of properties over those of the constituents. Despite its interesting mechanical and thermal properties, the impact strength of polypropylene leaves wide scope for improvement. A series of blends of ethylene vinyl acetate (EVA) copolymer with an impact grade of isotactic polypropylene (i-PP) were prepared by single screw extrusion at 0-0.32 volume fraction of the dispersed phase. The mechanical properties such as tensile behavior, elongation-at-break, and impact strength of these blends systems as well as crystallinity were evaluated. Crystallinity data have been used in greater depth to support the mechanical properties. Differential scanning calorimetry studies conducted to study the modification in crystallinity of the crystalline component, i-PP, of the blend revealed that the rubber component of the blend enhanced the crystallinity of i-PP phase by providing sites for nucleation. Tensile modulus and strength decreased while the impact strength and breaking elongation enhanced with blending elastomer concentration. The improved properties of these PP/EVA blends are encouraging for carrying out further work on this system (composites) and suggest potential high impact strength applications for PP.

“…Poly (butylene terephthalate) (PBT) sees wide application in such industries as automobile, electrical and electronics, and limited application for its poor low-temperature impact toughness and big notch sensitivity at room temperature [1][2][3][4] . These days, rubber (elastomer) and inorganic fibers are added together into the polymer to form the three-phase compound system, with a view to gain the high-performance low-cost compound material with the increased strength and toughness.…”
