“…[18][19][20]23 When the stearate-pretreated filler is added to SAN/EPDM blends, it is expected that the morphology of blends will become finer in comparison to the blends without filler. 24,25 This behavior is in accordance with SEM results (Fig. 2).…”

The properties of styrene–acrylonitrile (SAN) and ethylene–propylene–diene (EPDM) blends containing different types of calcium carbonate filler were studied. The influence of mixing type process on the blend properties was also studied. Two different mixing processes were used. The first one includes mixing of all components together. The other process is a two‐step mixing procedure: masterbatch (MB; EPDM/SAN/filler blend) was prepared and then it was mixed with previously prepared polymer blend. Surface energy of samples was determined to predict the strength of interactions between polymer blend components and used fillers. The phase morphology of blends and their thermal and mechanical properties were studied. From the results, it can be concluded that the type of mixing process has a strong influence on the morphological, thermal, and mechanical properties of blends. The two‐step mixing process causes better dispersion of fillers in blends as well as better dispersion of EPDM in SAN matrix, and therefore, the finest morphology and improved properties are observed in blends with MB. It can be concluded that the type of mixing process and carefully chosen compatibilizer are the important factors for obtaining the improved compatibility of SAN/EPDM blends. © 2012 Wiley Periodicals, Inc.

“…A mineral filler can act as a nucleating agent [7,[18][19][20] for crystallization, and can also reduce the mobility of the polymer chains close to it due to interactions with the surface of the fillers [9,21,22]. The presence of either micro or nanofillers can also lead to compatibilization in polymer blends either through an increase in the viscosity of the matrix [23][24][25][26], or through their presence at the interface [23,[27][28][29][30]. Under external load the particle agglomerates may induce stress concentrations that increase with their size [4,31,32], although this effect is less important in the case of nanoparticles.…”

“…Recent studies show that fillers can alter the phase stability and morphology of polymer blends [1][2][3][4]. Fillers of nanometric dimensions, such as silica, calcium carbonates, and layered silicates, are currently studied the most and they have been found to have compatibilization effects for immiscible polymer blends [5][6][7][8][9][10][11][12][13]. This idea is of importance to the theoretical study, and possesses a profound prospect in industrial application.…”

Polyamide 6 (PA6)/HDPE/organo-bentonite (Oclay) and PA6/HDPE-grafted-acrylic acid (PEAA)/Oclay nanocomposites were prepared via melt compounding. The influence of Oclay on the morphology of composites was investigated. Scanning electron microscopy results revealed the size of the dispersed HDPE, and PEAA phase decreased with increasing Oclay content. Transmission electron microscopy and X-ray diffraction results revealed that the Oclay was predominately intercalated with some evidence of partial exfoliation. The majority of Oclay platelets were concentrated in the PA6 phase and in the interfacial region between PA6 and HDPE (PEAA). The Oclay platelets played the role of coupling species between the two polymers, increasing the interaction of the two phases in certain extent. These results were proved by FTIR and positron annihilation lifetime spectroscopy. Consequently, apparent emulsifying effect was induced. A schematic mechanism of the apparent compatibilization effect was presented.
