“…According to the Figure 1, the complex viscosity decreased as the frequency increased, which clearly shows the pseudoplastic behavior of the blends, assuming the Cox Merz rule [46][47][48][49][50][51] . No significant differences were observed between the blends in relation to the exposure time of GTR to microwaves, and also whether or not [35] containing clay.…”

SbstractThe main objective of this work is to study the influence of clay addition on dynamically revulcanized blends of Ground Tire Rubber (GTR)/High Density Polyethylene (HDPE). GTR was previously devulcanized in a system comprised of a conventional microwave oven adapted with a motorized stirring, with a fixed microwave power and at various exposure times. The influence of clay addition on the final properties of the blends was evaluated in terms of mechanical, viscoelastic, thermal and rheological properties, with morphology being also analyzed. The results depict that the clay can modify the rheological behavior of the GTR phase, in addition to the thermal and mechanical properties of some blends.

“…Figure 2, the complex viscosity decreased with the increase of the frequency, which clearly shows the pseudoplastic behavior of the blends, assuming the Cox Merz rule [30][31][32][33][34][35] . η* of the dynamically revulcanized blends are higher than the blend 80GTR0/20HDPE due the increase of the cross-linking density of the GTR phase [35] .…”

SbstractThe main objective of this work is the study of the influence of microwaves devulcanization of the elastomeric phase on dynamically revulcanized blends based on Ground Tire Rubber (GTR)/High Density Polyethylene (HDPE). The devulcanization of the GTR was performed in a system comprised of a conventional microwave oven adapted with a motorized stirring at a constant microwaves power and at various exposure times. The influence of the devulcanization process on the final properties of the blends was evaluated in terms of mechanical, viscoelastic, thermal and rheological properties. The morphology was also studied.

“…η* increased with increasing PBAT content in the blends that attributed to the high cohesion between the PLA and the long branch chains of PBAT when existed 0.1% BIBP. All the curves presented evidence of shear‐thinning behavior with increasing frequency, indicating the pseudoplastic nature of the blends .…”

Blown films of poly(lactic acid) (PLA)/poly(butylene adipate‐co‐terephthalate) (PBAT) blends were prepared, bis(tert‐butyl dioxy isopropyl) benzene (BIBP) as crosslinking agent. From wide‐angle X‐ray diffraction results, PLA/PBAT/BIBP involved all the diffraction peaks were consistent with PLA and PBAT. For the DSC curves of PLA/PBAT/BIBP films, there were two glass transition temperature and two melt temperature, there existed two step decomposition in the thermogravimetric curves. Both Han plots and Cole–Cole plots indicated high homogeneity of the 40/60/0.1 PLA/PBAT/BIBP blend. SEM micrographs of the films revealed more ductile deformation with increasing PBAT content and 40/60/0.1 sample had better miscible compared with others. For the PLA/PBAT/BIBP films, tensile tests indicated that the elongation at break were increased with increasing PBAT content and the values of the tensile strength in the machine direction were higher than those in the transverse direction. The addition of PBAT, enhanced the toughness of the PLA/PBAT/BIBP films. From tear test and heat sealing test, the 40/60/0.1 PLA/PBAT/BIBP film exhibited the highest tear strength and the highest sealing strength among all the samples. POLYM. ENG.
