“…From ( Table 2) the values of (n) obtaining among vulcanized HDPE/GTR and HDPE/BP blends do not differ very much from pure HDPE value , such behavior was reported by George et al [19] and Oomenn et al [20], and they indicated that the addition of up to 20% of rubber does not affect markedly the flow behavior of polypropylene. And here it was found that the addition of 30% of GTR or PB also does not affect markedly the flow behavior of HDPE.…”

Thermoplastic elastomeric blends were prepared from blending of (10%, 20%, 30%, 40% and 50 wt%) high density polyethylene(HDPE) and (10%, 20%, 30%, 40% and 50 wt%) ground rubber tire (TPV-R). The blends prepared contain (HDPE)/polybutadiene (TPV-V). The two blends were successfully prepared through a dynamic vulcanization process, involving dicumyl peroxide (3%) as vulcanizing agent. The data of the mechanical (tensile strength at yield, %elonga-tion and young modulus) and rheological properties (shear stress, shear rate, viscosity, flow behavior index and activation energy of melt flow) of the TPV-V and TPV-R showed that there were comparable results between the two blends.

“…The rheological properties of NR/PMMA blend system with and without the addition of compatibilizer have also been studied. 10 The viscosity was found to increase with the addition of the graft copolymer and reaches a leveling off at the critical concentration of the graft copolymer.…”

“…Apart from raw NR, modified forms of NR have also been extensively used to prepare TPNRs. These include epoxidized natural rubber (ENR) [25][26][27], maleated natural rubber (MNR) [28,29], and natural rubber-g-poly(methyl methacrylate) [30][31][32].…”

Abstract:Blending of polymers provide an attractive route to obtain new materials with unique combination of properties. Among the possible blend morphologies are dispersion of droplet, fiber, lamella in continuous phase and cocontinuous morphology. The unique feature of co-continuous is the mutual interpenetration of the phases which exhibits a number of advantageous properties and hence wider range of applications. Therefore, it is important to perform accurate determination of the co-continuous phase morphology and phase inversion phenomena. The rubber co-continuity index (solvent extraction), SEM micrographs and dynamic properties indicated the inversion occurred in the blends with rubber content 40 to 50 wt%. Furthermore, three empirical models (i.e., Ultracki, Steiman et al and Gergen et al models) could predict the phase continuity and phase inversion phenomena but other two (i.e., Paul-Barlow and MetelkinBlekht models) failed. Therefore, based on rubber co-continuity index, SEM micrographs, dynamic mechanical properties and prediction, the inversion phenomena occurred in the blends with rubber contents in a range of 40-50 wt%. Full co-continuity was found in the blends with the rubber contents of 46 to 60 wt%.
