“…If the blend is readily miscible and homogeneous, the curves η″ = f (η′) are quite smooth and have the shape of a semicircle. However, the occurrence of deviations or disordered points on the curve can reflect a poor homogeneity of the blends components . Figure (a) presents plots of η″ versus η′ for the ABS/PC blends obtained by extrusion processing.…”

“…Thus, the final properties of the resulting blend depend on the degree of miscibility between components, composition, solvent, and morphology of the blend . But generally, blends of polymers present immiscibility or a partial miscibility due to the large size of the polymer chains and the high interfacial tension between the segregated phases or because of the poor adhesion between the two polymer phases . According to the principles of thermodynamics, when the free energy of mixing is negative, the thermodynamic miscibility and homogeneity can be reached.…”

In the challenging prospect of developing new materials by mixing different polymers to reach a synergetic performance, the present research focuses on the study of the miscibility of two polymers: The acrylonitrile butadiene styrene (ABS) composed of a dispersed elastomeric (polybutadiene rubber) polymer embedded in a SAN thermoplastic matrix, and the polycarbonate (PC). It shall be noted that obtaining miscible polymer blends is often a difficult task because of the large size of their molecular chains and the high interfacial tension between the polymer phases. Until now, the most numerous researches developed in this field involve polymer blends obtained by compatibilization techniques in order to improve the interfacial adhesion between initial polymers. The aim of this work is to study the miscibility between ABS and PC. First, two different methods were used to mix the polymers: the twinscrew extrusion and the dissolution in a common solvent tetrahydrofuran (THF). Then, physicochemical, microscopic observation and rheological characterization were performed on samples of mixtures obtained by both extrusion processing and dissolution method. The measurement of glassy transition temperature (T g ) by differential scanning calorimetry measurements (DSC) and dynamical mechanical thermal analysis (DMTA) have shown a partial miscibility between the two polymers.

“…As can be seen in Fig. 3, systems prepared with Cl20 and Cl20/ZnO show spatial structure similar to mentioned LCB polymers with even two bumps or peaks (Cl20), indicating complex 3D structure made of filler and polymer chains [49]. The CA9150 matrix and nanocomposite with ZnO exhibit behaviour connected with linear chain structure.…”

multiphase polymer systems, like polymer nanocomposites, exhibit complex rheological behaviour due to physical and also possibly chemical interactions between individual phases. up to now, rheology of dispersive polymer systems has been usually described by evaluation of viscosity curve (shear thinning phenomenon), storage modulus curve (formation of secondary plateau) or plotting information about dumping behaviour (e.g. van Gurp-Palmen-plot, comparison of loss factor tan δ). on the contrary to evaluation of damping behaviour, values of cot δ were calculated and called as "storage factor", analogically to loss factor. then values of storage factor were integrated over specific frequency range and called as "cumulative storage factor". in this contribution, LDPe-zno-clay nanocomposites with different dispersion grades (physical networks) have been prepared and characterized by both conventional as well as novel analysis approach. next to cumulative storage factor, further cumulative rheological parameters like cumulative complex viscosity, cumulative complex modulus or cumulative storage modulus have been introduced.

“…The association of PE-g-MAH at the interface of two different matrixes resulted in lowered interfacial tension of the blends, therefore increasing the modulus values. 3 However, from Figure 5, the addition of CL-MAH increased the modulus of elasticity just for the blend composition of RHDPE80/EVA20, while the rest of the blend composition showed decreasing modulus of elasticity with addition of CL-MAH. The reasoning behind this could be that the compatibilising effect was restricted merely to the amorphous part of EVA that would reduce the modulus value accordingly.…”

“…These segregated phases act as a barrier to an effective stress transfer between the phases, and uneven morphology shows poor adhesion between the phases leading to the poor mechanical properties of the final blends. 3,4 Compatibilisation of an immiscible polymer blend can be done by altering the interfacial properties which can result in the formation of the interphase and stabilise the blend morphology. The uniform blend can be attained with the help of compatibiliser, an additive which added in polymer blends to improve the adhesion and interaction between two components of polymer.…”
