“…Their result shows that the finest PET domain was at 10 wt% of PP‐g‐MAH. The reaction of ester groups of MAH with the PET/PP blends during melt mixing increased the tensile strength, tensile modulus, and elongation at break of the blends . Champagne et al have studied PET/PP blends compatibilized with PP grafted glycidyl methacrylate and observed that the use of the modifier changed the tensile behavior from fragile to ductile, increased the tensile strength by 10%, and improved elongation at break by 10 to 20‐fold.…”

Polyethylene terephthalate (PET) and polypropylene (PP) are incompatible thermoplastics because of differences in chemical structure and polarity, hence their blends possess inferior mechanical and thermal properties. Compatibilization with a suitable block/graft copolymer is one way to improve the mechanical and thermal properties of the PET/PP blend. In this study, the toughness, dynamic mechanical analysis (DMA), and thermogravimetric analysis (TGA) of PET/PP blends were investigated as a function of different content of styrene-ethylene-butylene-styrene-g-maleic anhydride (SEBS-g-MAH) compatibilizer. PET, PP, and SEBS-g-MAH were melt-blended in a single step using the counter rotating twin screw extruder with compatibilizer concentrations of 0, 5, 10, and 15 phr, respectively. The impact strength of compatibilized blend with 10 phr SEBS-g-MAH increased by 300% compared to the uncompatibilized blend. Scanning electron microscope (SEM) micrographs show that the addition of 10 phr SEBS-g-MAH compatibilizer into the PET/PP blends decreased the particle size of the dispersed PP phase to the minimum level. The improvement of the storage modulus and the decrease in the glass transition temperature of the PET phase indicated an interaction among the blend components. Thermal stability of the PET/PP blends was significantly improved because of the addition of SEBS-g-MAH. J. VINYL ADDIT. TECHNOL., 23:45-54, 2017.

“…And yet, polymer/graphene masterbatch during preparation still did not completely avoid the use of organic solvents. To solve this problem, reactive extrusion can provide a good way for the preparation of graphene/polymer masterbatch, which has been widely used for the industrial synthesis of polyolefin grafted polyester copolymers by melt phase processing …”

A reactive extrusion process was developed to fabricate polymer/graphene nanocomposites with good dispersion of graphene sheets in the polymer matrix. The functionalized graphene nanosheet (f-GNS) activated by diphenylmethane diisocyanate was incorporated in thermoplastic polyester elastomer (TPEE) by reactive extrusion process to produce the TPEE/f-GNS masterbatch. And then, the TPEE/f-GNS nanocomposites in different ratios were prepared by masterbatchbased melt blending. The structure and morphology of functionalized graphene were characterized by Fourier transform infrared, X-ray photoelectron spectroscopy, X-ray diffraction and transmission electron microscopy (TEM). The incorporation of f-GNS significantly improved the mechanical, thermal and crystallization properties of TPEE. With the incorporation of only 0.1 wt% f-GNS, the tensile strength and elongation at break of nanocomposites were increased by 47.6% and 30.8%, respectively, compared with those of pristine TPEE. Moreover, the degradation temperature for 10 wt% mass loss, storage modulus at À70°C and crystallization peak temperature (T cp ) of TPEE nanocomposites were consistently improved by 17°C, 7.5% and 36°C. The remarkable reinforcements in mechanical and thermal properties were attributed to the homogeneous dispersion and strong interfacial adhesion of f-GNS in the TPEE matrix. The functionalization of graphene was beneficial to the improvement of mechanical properties because of the relatively well dispersion of graphene sheets in TPEE matrix, as suggested in the TEM images. This simple and effective approach consisting of chemical functionalization of graphene, reactive extrusion and masterbatch-based melt blending process is believed to offer possibilities for broadening the graphene applications in the field of polymer processing.

“…Polyethylene terephthalate (PET) and polypropylene (PP) are known to be fully immiscible and require interfacial modification to obtain good emulsification and to increase the solid‐state adhesion. Numerous investigations have been performed to compatibilize PET and PP with different types of compatibilizer containing maleic anhydride (MA), acrylic acid, or glycidyl methacrylate functionality 13–17. The incorporated compatibilizer decreases the interfacial tension between PET and PP, thus leading to a finer morphology of the blends 18.…”

in Wiley InterScience (www.interscience.wiley.com).ABSTRACT: Uncompatibilized and compatibilized (polypropylene grafted maleic anhydride as compatibilizer) polyethylene terephthalate (PET)/polypropylene (PP)/TiO 2 microfibrillar composites (MFC) were prepared by injection molding of the pelletized PET/PP/TiO 2 drawn strands. The morphology of PET fibrils and the distribution of TiO 2 particles in the composites were examined. After injection molding the preferential location of TiO 2 particles is still preserved. Because of the reinforcement effect of PET fibrils, the tensile properties and impact strength of the PET/PP MFC are improved compared with the pure PP. Incorporation of TiO 2 particles results in decrease of both tensile strength and impact strength of the composites. However, the compatibilized PET/PP/ TiO 2 MFC demonstrate better mechanical properties compared with the uncompatibilized ones. DMA analysis shows that the glass transition temperature (T g ) of PET in the uncompatibilized PET/PP/TiO 2 MFC and the T g of PP in the compatibilized PET/PP/TiO 2 MFC are elevated by about 2 C. The elevation of T g is attributed to the preferential location of TiO 2 particles in the composites.
