“…Besides compatibilizer, selective localization of fillers in binary blends stabilizes the phase morphology and result in interesting blend properties. It was extensively reported in the past that an efficient way to toughen polyamides is to blend with rubbery phase (like ABS) [22,23]. Thus, in order to investigate the effect of MWNT on the mechanical properties of the 50/50 PA6/ ABS blends, we have carried out tensile tests and the fracture surfaces are investigated by microscopic techniques.…”

The mechanical and the crystallization behavior of melt-mixed cocontinuous blends of polyamide6 (PA6) and acrylonitrile butadiene styrene were studied in presence of multiwall carbon nanotubes (MWNT). Young's modulus was observed to be significantly improved with increasing concentration of MWNT, while only moderate improvements were observed in the tensile strength. To overcome the van der Waals' forces between MWNT a unique modifier, sodium salt of 6 amino hexanoic acid (Na-AHA) was employed where it was envisaged that specific interactions between Na + of the modifier and the delocalized ''pelectron'' clouds of MWNT would lead to significant debundlling of the tubes. The mechanical properties of the blends with Na-AHA modified MWNT were found to be improved as compared to the blends with purified MWNT however, were found to be adversely affected above certain concentration of Na-AHA in the blends. Dynamic mechanical thermal analysis supported the plasticization effect induced by Na-AHA manifesting in decrease in the glass transition temperature of PA6 in the blends with Na-AHA modified MWNT. Differential scanning calorimetry results showed two crystallization exotherms for PA6 in the blends with both purified and Na-AHA modified MWNT. This unusual crystallization behavior of PA6 was addressed in context to confined crystallization of PA6 in the tube ''network-like'' structure.

“…The use of ABS to modify some of the properties of PA6 was reported in the past. [21][22][23][24][25][26][27][28][29] The concept of reactive compatibilization and the use of styrene-maleic anhydride copolymer (SMA) as an effective compatibilizer for PA6/ABS system was described extensively. [29][30][31][32] Recently carbon nanotubes have emerged as a potential candidate as filler in polymer based composites because of their unique mechanical, electrical, and thermal properties.…”

Blends of polyamide6 (PA6) and acrylonitrile butadiene styrene (ABS) were prepared in presence or absence of up to 5 wt % of a reactive compatibilizer [styrene maleic anhydride copolymer (SMA) modified with 5 wt % multiwall carbon nanotubes (MWNT)] by meltmixing using conical twin screw microcompounder where the ABS content was varied from 20 to 50 wt %. The melt viscosity of the blends was significantly enhanced in presence of SMA modified by multiwall carbon nanotubes due to the reactive compatibilization, which leads to stabilized interphase in the blends. Furthermore, the presence of MWNT in the compatibilizer phase led to additional increase in viscosity and storage modulus. Morphological studies revealed the presence of either droplet-dispersed or cocontinuous type depending on the blend compositions. Further, reactive compatibilization led to a significant change in the morphology, namely a structure refining, which was enhanced by MWNT presence as observed from SEM micrographs. DSC crystallization studies indicated a delayed crystallization response of PA6 in presence of ABS presumably due to high melt viscosity of ABS. The crystallization temperature and the degree of crystallinity were strongly dependent on the type of morphology and content of reactive compatibilizer, whereas the presence of MWNT had an additional influence. SAXS studies revealed the formation of thinner and less perfect crystallites of PA6 phase in the blends, which showed cocontinuous morphology. A unique observation of multiple scattering maxima at higher q region has been found in the blends of cocontinuous morphology, which was observed to be successively broadened in presence of the compatibilizer.

“…A particularly strategy is the addition of a polymer that is miscible with the styrene–acrylonitrile (SAN) phase and that can react with the amine end groups of the nylon phase. Several works have been conducted with the PA6/ABS blend 2, 4–17. There has been much interest in the use of glycidyl methacrylate (GMA)‐ and maleic anhydride (MA)‐based copolymers as compatibilizing agents for polymer blends.…”

ABSTRACT:Polymer alloys have been used as an alternative to obtain polymeric materials with unique physical properties. Generally, the polymer mixture is incompatible, which makes it necessary to use a compatibilizer to improve the interfacial adhesion. Nylon 6 (PA6) is an attractive polymer to use in engineering applications, but it has processing instability and relatively low notched impact strength. In this study, the acrylonitrile-butadiene-styrene (ABS) triblock copolymer was used as an impact modifier for PA6. Poly(methyl methacrylate-co-maleic anyhydride) (MMA-MA) and poly(methyl methacrylate-co-glycidyl methacrylate) (MMA-GMA) were used as compatibilizers for this blend. The morphology and impact strength of the blends were evaluated as a function of blend composition and the presence of compatibilizers. The blends compatibilized with maleated copolymer exhibited an impact strength up to 800 J/m and a morphology with ABS domains more efi8ciently dispersed. Moderate amounts of MA functionality in the compatibilizer (ϳ5%) and small amounts of compatibilizer in the blend (ϳ5%) appear sufficient to improve the impact properties and ABS dispersion.
