“…Although the anhydride group interacts with the ester group of PET, the ethylene‐butylene mid‐group is affined to the PP . Several studies have been conducted on the compatibilization of PET/PP blends by SEBS‐g‐MAH , the toughening of PET by SEBS‐g‐MAH , or toughening of PET nanocomposites . In our previous study , we compared the effect of two compatibilizers, namely SEBS‐g‐MAH and PP‐g‐MAH, on the morphology and mechanical properties of PET/PP blends.…”

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.

“…[51] PS grafts were also synthesized by styrene radical polymerization onto irradiated PC from created radical sites. [52][53][54][55][56][57][58][59][60][61][62] SEBS-g-MAH is a preformed immiscible terpolymer, with PC, widely used in the field of compatibilization of styrenic polymers, polyolefins, and polyamides. But this terpolymer was never used to compatibilize PC/ PS blends.…”

The reactions between polycarbonate (PC) and polystyrene-block-poly(ethylene-butylene)-block-polystyrene-graftedmaleic anhydride (SEBS-g-MAH) is a novel, convenient, solvent-free, and easy way to create SEBS-g-PC in order to compatibilize polystyrene and PC blends. This study determines the most efficient catalyst among Tin (II) bis(2-ethylhexanoate) (SnOct 2 ), 1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD), Titanium tetrabutoxide (Ti(OBu) 4 ) and Sodium 4-hydroxybenzenesulfonate dihydrate (SHBS) in the molten state at 220°C. From 20 to 30 wt% of SEBS-g-MAH (or KFG) chains became insoluble. The size exclusion chromatography analyses showed the formation of a double distribution due to PC chains scission and grafting reactions onto SEBS-g-MAH with the exception of the Ti(BuO) 4 use. Fine microstructures with a percolation effect proved the efficiency of both the TBD and the SnOct 2 . The PC transition temperature decreased in at least 10°C, confirmed that only SnOct 2 and TBD were efficient to catalyze the grafting reactions. No evolution was observed with the SHBS and Ti(OBu) 4.

“…PET may enhance the stiffness of PP at higher temperatures while the polyolefin could facilitate crystallization of PET by heterogeneous nucleation, further raising blend stiffness [4,5] . In addition, the lower permeability of PET towards water vapor and oxygen could be usefully utilized in packaging materials, as the adequate morphology of the blend is achieved [4,6] .…”

The compatibilization of recycled PP/PET blend with high and low concentration (20 and 5 phr) of elastomer functionalized by maleic anhydride (SEBS-g-MA) was achieved. Recycled polypropylene from plastic industry and recycled PET from post-consumer bottles was used. PP/PET blends: 80:20 w/w, 50:50 w/w and 20:80 w/w were prepared in an internal mixer for mechanical properties, thermal properties, morphology and rheological properties. SEBS-g-MA promoted compatibilization of the PP/PET blends and improved their properties. With an increasing compatibilization level, the refinement of morphology was observed in the PET rich blend. Compatibilized blends showed negative deviation in the PET glass transition temperature related to neat PET, demonstrating that compatibilization was very successful. PET crystallization was accelerated in the blends due to PP presence that enhanced nucleation. It was found that the 50/50/20 blend showed huge potential for textile fiber application and that of 80/20/20 showed more intermediary properties than neat polymers.
