“…Nevertheless, in the last few years, these theoretical models have been successfully applied to a number of polyblend systems. [16][17][18] The models are currently available both for poor and perfect adhesion between the matrix and dispersed phases.…”

Summary: Blends of poly(acrylonitrile‐butadiene‐styrene) (ABS) and poly(ether ether ketone) (PEEK), in which PEEK has been used as a reinforcing medium for the ABS matrix in ratios up to 20 wt.‐% of the blend, were prepared by melt mixing using a laboratory mixer. All the blend compositions were processed at the ABS processing temperature so that the PEEK was dispersed in the ABS matrix without actually melting. Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) studies revealed that the glass transition temperature (Tg) of the ABS phase in the blend did not show any appreciable change with composition. The dynamic storage modulus measured by DMA was found to be higher for the blend as compared to pure ABS due to reinforcement of the matrix by PEEK. The tensile strength and modulus behavior of these blends were found to follow the curves predicted using models proposed for composite systems having perfect adhesion, which shows the presence of some physical interaction between the blend components. The good tensile properties of the blend have been correlated with the observed morphology. The disperse phase in the blend has been found to be present in extremely small (sub‐micron) dimensions, which not only provides more surface area for possible interactions between the blend components but also result in efficient stress transfer between the matrix and the dispersed phase during the tensile tests. The thermal stability of the blends was investigated using thermogravimetric analysis (TGA). TGA further revealed that the constituents degraded at their respective decomposition temperatures.SEM micrograph of tensile fractured surface of an ABS/PEEK 90/10 blend.magnified imageSEM micrograph of tensile fractured surface of an ABS/PEEK 90/10 blend.

“…The NR/SBR compounds belong to the category of immiscible or partially miscible blends because the presence of two phases is detected in these materials [2][3][4]. However, blending process has a strong influence on the final rheological properties according to the phase morphology and the dispersion and distribution of the fillers achieved.…”

“…The better the compatibilization, the closer the peaks related to the glass transition of the components. [14][15][16][17][18] When the rubbers components were blended, even upon the addition of TOR or with an increase in the mixing time, the temperatures at which the maxima of tan d occurred did not change, which indicated the strong immiscible character of the rubber forming the compounds.…”

In this study, the influence of the processing conditions and the addition of trans-polyoctenylene rubber (TOR) on Mooney viscosity, tensile properties, hardness, tearing resistance, and resilience of natural rubber/styrene-butadiene rubber blends was investigated. The results obtained are explained in light of dynamic mechanical and morphological analyses. Increasing processing time produced a finer blend morphology, which resulted in an improvement in the mechanical properties. The addition of TOR involved an increase in hardness, a decrease in tear resistance, and no effect on the resilience. It resulted in a large decrease in the Mooney viscosity and a slight decrease in the tensile properties if the components of the compounds were not properly mixed. The results indicate that TOR acted more as a plasticizer than a compatibilizer.
