“…This was due to the formation of small E-GMA droplets by an excess of compatibilizer, which tends to co-exist with the large HDPE domains. The poor intrinsic mechanical properties of E-GMA could be another possible reason for the reduced tensile and flexural properties [11]. The compatibilizing role of E-GMA for rHDPE/rPET blends can be confirmed by the toughening behaviour, which implies for SB of blends [18].…”

“…Graft copolymer containing MAs such as MA grafted polyethylene (PE-g-MA) [4] [7] [9], HDPE-g-MA [10] and MA grafted styrene-ethylene-butenestyrene copolymer (SEBS-g-MA) [9] [10] have been reported. Whilst, random copolymer containing GMA such as HDPE-g-GMA [10], E-GMA [9] [11], ethylene-ethyl acrylate-glycidyl methacrylate (E-EA-GMA) [11] and ethylene-butyl acrylate-glycidyl methacrylate (EBAGMA) [12] are commonly used for investigation.…”

“…Second, epoxy function of GMA has higher reactivity than MA towards hydroxyl groups of PET. Lastly, the esterification reaction is reversible at high temperatures [11] [13]. The objective of this study was to investigate the influence of rHDPE-rich blend composition and compatibilizer loading levels on the mechanical properties and morphology stability of resultant blends.…”

Polymer blends based on recycled high density polyethylene (rHDPE) and recycled poly(ethylene terephthalate) (rPET) with and without ethylene-glycidyl methacrylate copolymer (E-GMA) as compatibilizer were fabricated in a co-rotating twin screw extruder. The effects of rPET and compatibilizer content on the mechanical properties and morphological stability of rHDPE-rich blends were investigated. The rHDPE/rPET (75/25 wt/wt) blend compatibilized with 5 php (per 100 part of polymer) E-GMA showed an enhancement of about 7% -26% in tensile properties and flexural strength as compared with those of the neat rHDPE. The strain at break showed a decreasing trend as the rPET content increased. The addition of E-GMA to the rHDPE/rPET blends was found to recover the blend toughness as well as improving the compatibility between HDPE and PET. In this study, the highest strain at break was obtained for the rHDPE/rPET blends at 75/25 (wt/wt) composition with E-GMA content of 5 php. FTIR and SEM analysis of the compatibilized blends confirmed the chemical interaction and improved interfacial bonding between the two phases.

“…Figures 7 and 8 show that HDPE appeared as an island or in droplet form surrounded by the molten rPET phases. This is because HDPE with a higher viscosity has the opportunity to form agglomeration into an island form in the molten rPET phase [21,22]. The virgin HDPE with long molecular chains was forced to agglomerate because of limited mobility.…”

The objective of this research is to investigate the effect of incorporating montmorillonite (MMT) on the mechanical, morphological, rheological, and thermal properties of recycled poly(ethylene terephthalate) (rPET) and high-density polyethylene (HDPE) nanocomposites. The MMT contents in 90:10 rPET/HDPE and 70:30 rPET/ HDPE ranged from 1 to 5 wt.%. rPET/HDPE nanocomposites were prepared by using a single screw extruder, and injection molded to prepare mechanical test specimens. The samples underwent rheological tests by using a capillary rheometer, and the morphology of the nanocomposites was investigated by scanning electron microscopy (SEM). The thermal stability of the nanocomposites was tested using thermogravimetric analysis (TGA). The results showed that MMT acts as compatibilizing agent and improves phase dispersion and interfacial adhesion in the nanocomposites. The maximum tensile strength was found at 3 and 1 wt.% of MMT for the 90:10 and 70:30 rPET/HDPE blends. However, the tensile modulus decreased significantly with the incorporation of MMT. The impact strength for both the 90:10 and 70:30 blends reached a maximum at 3 wt.% and started to decrease beyond 3 wt.%. The incorporation of MMT increased the shear viscosity of the 90:10 and 70:30 blends, which reached a maximum value at 3 and 1 wt.%. SEM micrographs showed a good interaction of MMT that improved the adhesion between the two phases of blends and led to an increase in the mechanical properties of rPET/HDPE nanocomposites.

Rice husk flour (RHF) biocomposites based on uncompatibilized and compatibilized recycled high density polyethylene/recycled polyethylene terephthalate (rHDPE/rPET) with ethylene‐glycidyl methacrylate (E‐GMA) copolymer were prepared through a two‐step extrusion and hot pressing with fiber loadings of 40, 60, and 80 wt %. Results showed that tensile and flexural properties increased. However, the elongation to break and impact strength decreased as the RHF loading increased. Compatibilizing polymer blend matrices can further enhance the mechanical properties. Water absorption (WA) test were examined in distilled and seawater. It is interesting to note that for composites made from uncompatibilized matrix, the calculated D and KSR were lower in seawater, but for the compatibilized matrix composites, the D and KSR obtained were generally lower in distilled water. However, compatibilization of rHDPE/rPET has been markedly reduced the WA and thickness swelling. Scanning electron microscope analysis of the compatibilized matrix composites confirmed the improved interfacial bonding of matrix–matrix and filler–matrix phases. © 2014 Wiley Periodicals, Inc. J.
