“…The composition depen-dence of tensile strength and modulus are shown in Figure 2 and Figure 3, respectively. These observations are similar to those by Hourston et al in the 16 case of PBT/unsaturated rubber blends. The elongation at break was, however, found to increase from 27 to 39% with increase in VLDPE content, as illustrated in Figure 4.…”

Blends of polybutylene terephthalate (PBT) with very low‐density polyethylene (VLDPE) have been studied. The blends are immiscible owing to the differences in the polarities of the component polymers. Thermal studies using a differential scanning calorimeter showed that the blending does not change the crystallinity and non‐isothermal crystallization behavior of PBT. The tensile strength and modulus showed gradual decrease with increase in VLDPE content. The impact strength, however, was found to increase marginally with increasing VLDPE content. The examination of fractured surfaces using scanning electron microscopy indicated a two‐phase morphology with spherical domains of VLDPE dispersed in PBT matrix. Addition of ethylene‐based compatibilizers resulted in significant improvements in the mechanical properties through modification of phase morphology and interfacial adhesion. The effectiveness of the compatibilizers has been explained on the basis of possible interaction between the reactive groups present in the compatibilizer and the polymer. The presence of such bonding reaction leading to better interfacial properties has also been confirmed using lap shear measurements. © 2000 John Wiley & Sons, Inc. Adv Polym Tech 19: 41–53, 2000

“…Polyolefins and poly(alkyl terephthalate) are considered to be immiscible and incompatible. Only a very limited number of studies on these blends have been reported; however, they have received considerable interest lately 1–12. Polypropylene (PP) is neither miscible nor compatible with poly(butylene terephthalate) (PBT) due to a great difference in polarity.…”

In this study, dual compatibilizers composed of the commercially available maleic anhydride‐grafted polypropylene (PP–MA) and a multifunctional epoxy resin were demonstrated to effectively compatibilize the immiscible and incompatible blends of PP and poly(butylene terephthalate) (PBT). The PP–MA with a low MA content is totally miscible with PP to make the PP phase quasi‐functionalized, so that the multifunctional epoxy has the chance to react with PBT and PP–MA simultaneously to form PP–MA‐co‐epoxy‐co‐PBT copolymers at the interface. These desired copolymers are able to anchor along the interface and serve as efficient compatibilizers. The compatibilized blends, depending on the quantity of dual compatibilizers employed, exhibit higher viscosity, finer phase domain, and improved mechanical properties. Epoxy does not show compatibilization effects for the PP/PBT blends without the presence of PP–MA in the blends. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 79: 2272–2285, 2001
