“…[16][17][18][19] Figure 5 shows the dependence of steady shear viscosity on shear rate of PPE/PETG blend with various compositions at 280 • C. The PPE/PETG blends exhibit a shear thinning behavior, i.e., a decrease in shear viscosity with an increase in shear rate. [20] In addition, as more PPE was added, the shear viscosity of samples was increased in the low shear rate region.…”

Polyphenylene ether (PPE)/glycol modified polyethylene terephthalate (PETG) blends with various compositions were fabricated via a melt blending method using a laboratory-scale twin-screw extruder. The fracture surface morphology of the PPE/ PETG blends was examined by scanning electron microscopy (SEM) and, based on its data, it was observed that PPE and PETG are immiscible. Thermal stability and mechanical properties of the blends were also examined via thermal gravimetric analysis and a universal testing machine (UTM), respectively. Rheological properties of the PPE/PETG blends were observed with both steady shear and dynamic tests using a rotational rheometer. The effect of poly(styrene-co-maleic anhydride) (SMA) as a compatibilizer on the PPE/PETG blends was additionally investigated. An increase in quantity of PPE in the PPE/PETG blends and the addition of SMA were observed to enhance their thermal and mechanical properties.

“…Moreover, the reactive extrusion of polymers was performed in the presence of the solid multi-functional epoxy compound, Joncryl TM (a trade name of the BASF Company) as a chain extender. Joncryl TM has been extensively used as a chain extender for polyester blends, where it reconnects the cleaved chains that are formed by thermal degradation during thermal processing so as to achieve high molecular weight polyesters and subsequently improve their melt strength [19,[22][23][24][25].…”

This study aimed to improve the brittleness and thermal stability of poly(lactic acid) (PLA) by inclusion of poly(butylene succinate) (PBS) and microcrystalline cellulose (MCC). Of the three PLA/PBS blends (10, 30 and 50 wt% PBS) evaluated, the 70/30 wt% blend exhibited the highest impact strength and elongation at break, but a lower thermal stability compared to that of the pure PLA. Scanning electron microscopy analysis confirmed the better compatibility of this 70/30 PLA/PBS blend. This blend was further filled with MCC. Based on thermogravimetric analysis, the thermal stability of the 70/30 PLA/PBS blend was improved by the addition of MCC [optimal at five parts by weight per hundred (phr)] and further still by the addition of the chain extender, Joncryl TM , at 0.5 phr. The 70/30/5/0.5 PLA/PBS/MCC/Joncryl TM composite exhibited the highest impact strength, while the elongation at break was acceptable.

“…In order to improve tensile strength and modulus of the blends, fillers, such as multi-walled carbon nanotubes (MWNTs) [26] , montmorillnite clay (MMT) [23,27] , and calcium carbonate (CaCO 3 ) [27] were incorporated into the blends. CaCO 3 is commonly used as inorganic filler in polymer.…”

Poly(lactic acid) (PLA)/poly(butylene adipate-co-terephthalate) (PBAT) blends and their composite were prepared by melt compounding. Maleic anhydride grafted PLA (PLA-g-MA) was used as a compatibilizer. With the addition of PBAT into PLA, elongation at break and impact strength increased but tensile strength and modulus decreased. Incorporating PLA-g-MA into PLA/PBAT blend improved the mechanical properties of the blend. Tensile properties of blown film prepared from the compatibilized PLA/PBAT blend were better than those of the uncompatibilized PLA/PBAT blend. Incorporating CaCO 3 resulted in increased tensile strength and modulus of the film prepared from the compatibilized blend.
