“…In many cases blends of polyolefin and PET are compatibilized by introducing a polymer bearing groups reactive towards PET terminal groups [24e28]. In this case degradation affects the type and concentration of terminal groups which can influence the extent of compatibilization reaction occurring at the interface between the two immiscible phases [29,30], determining the final structure of the formed polyolefinePET copolymer. With the aim of investigating these aspects, PET scraps were blended in different operative conditions with dibutyl maleate functionalized polyethylene in order to evaluate the effect of blending conditions on reactive compatibilization and phase morphology development.…”

“…After melt annealing and cooling at 10 C/ min, the crystallization peak temperature (T c ) found was 190. 4 C. For R-HDPE, the melting peak and crystallization peak appeared at 133.9 and 112.0 C, respectively. The DSC cooling curves for pure R-HDPE, R-PET, and their uncompatibilized binary blends are shown in Figure 6(b).…”

“…3,22 For example, Coltelli et al functionalized SEBS with diethyl maleate (DEM) or 2-hydroxyethyl methacrylate and added them to LDPE/R-PET (80/20) blends in the presence of Ti(OBu) 4 as transesterification catalyst. 4 The phase distribution depended strongly on composition, and, in particular, the preferential dispersion of R-PET in the SEBS-g-DEM was obtained when at least 40% by weight of LDPE was replaced by SEBS-g-DEM. Pracella et al 5,6 compatibilized R-HDPE/R-PET (25/75) blends by melt-mixing in the presence of various functionalized polyolefins (e.g., HDPE-g-MA, EPR-g-MA, E-AA, E-GMA, and SEBS-g-MA).…”

“…Also, a high loading of functional elastomer-based compatibilizer (e.g., 10-20 pph) was necessary to significantly improve toughness of the blends. [4][5][6][7][8][9][10]16,21 Post-consumer PET undergoes a reduction in intrinsic viscosity or molar mass when recycled in a normal extrusion system because of thermal and hydrolytic degradation. This can result in significantly lower mechanical properties, especially tensile properties.…”

Blends based on recycled high density polyethylene (R-HDPE) and recycled poly(ethylene terephthalate) (R-PET) were made through reactive extrusion. The effects of maleated polyethylene (PE-g-MA), triblock copolymer of styrene and ethylene/butylene (SEBS), and 4,4 0 -methylenedi(phenyl isocyanate) (MDI) on blend properties were studied. The 2% PE-g-MA improved the compatibility of R-HDPE and R-PET in all blends toughened by SEBS. For the R-HDPE/R-PET (70/30 w/w) blend toughened by SEBS, the dispersed PET domain size was significantly reduced with use of 2% PE-g-MA, and the impact strength of the resultant blend doubled. For blends with R-PET matrix, all strengths were improved by adding MDI through extending the PET molecular chains. The crystalline behaviors of R-HDPE and R-PET in one-phase rich systems influenced each other. The addition of PE-g-MA and SEBS consistently reduced the crystalline level (v c ) of either the R-PET or the R-HDPE phase and lowered the crystallization peak temperature (T c ) of R-PET. Further addition of MDI did not influence R-HDPE crystallization behavior but lowered the v c of R-PET in R-PET rich blends. The thermal stability of R-HDPE/R-PET 70/30 and 50/50 (w/w) blends were improved by chain-extension when 0.5% MDI was added.

“…Functionalized grades of SEBS containing maleic anhydride (MA),7–9 glycidyl methacrylate,9 and diethyl maleate10 have been used. SEBS has also been functionalized with 2‐hydroxyl ethyl methacrylate to obtain a more reactive compatibilizer precursor 10. Reactive copolymers have also been tested successfully.…”

Blends of low-density polyethylene (LDPE) and poly(ethylene terephthalate) (PET) were prepared with different weight compositions with a plasticorder at 2408C at a rotor speed of 64 rpm for 10 min. The physicomechanical properties of the prepared blends were investigated with special reference to the effects of the blend ratio. Graft copolymers, that is, LDPE-grafted acrylic acid and LDPE-grafted acrylonitrile, were prepared with cirradiation. The copolymers were melt-mixed in various contents (i.e., 3, 5, 7, and 9 phr) with a LDPE/PET blend with a weight ratio of 75/25 and used as compatibilizers. The effect of the compatibilizer contents on the physicomechanical properties and equilibrium swelling of the binary blend was investigated. With an increase in the compatibilizer content up to 7 phr, the blend showed an improvement in the physicomechanical properties and reduced equilibrium swelling in comparison with the uncompatibilized one. The addition of a compatibilizer beyond 7 phr did not improve the blend properties any further. The efficiency of the compatibilizers (7 phr) was also evaluated by studies of the phase morphology (scanning electron microscopy) and thermal properties (differential scanning calorimetry and thermogravimetric analysis
