“…In all probabilies the immiscible phases are the cause for the weak mechanical properties. That theory have been described by others, who concluded that in case of PP/PA 6 blends the poor mechanical and other properties could be blamed with weak interfacial forces due to the immiscible phases 12–19. In Figure 5(b–d) the fractured structure of additive containing blends are shown, where more homogenous phase was found.…”

“…In polymer developments the blending of two or more polymers is a widely investigated area, but the multiphase polymer morphology generally leads to both poor chemical and physical interactions across the phases. Many researchers investigate the possibility of compatibilization techniques to increase the interfacial adhesion in polymer blends; generally in thermoplastics 10–27. Market for thermoplastics is dominated by polypropylene and polyethylene.…”

The present article discloses the properties improvement in PP/PA 6 blends by new type experimental coupling additives. By the experimental agents especially the tensile properties could be improved. For example, the tensile strength and the elongation were 16.5 MPa and 4.4% without additive, which increased to 25.5, 20.1, 46.8 MPa and 8.1, 6.4,8.6% in specimens containing polyalkenyl-poly-maleic-anhydride-amide, polyalkenyl-poly-maleic-anhydride-ester, and MA-grafted-low-polymer additives, respectively. DSC curves shows that compatibilizers influenced thermal properties of the polymer blends and reveal affecting of crystalline phase formation process in the blends due to the compatibilization step. Additives A and B rather leads to influencing of PA crystallinities. According to the SEM and FTIR analysis well separated polypropylene and polyamide phases was observed in case of specimens absence of additives but only one well distributed phase by the applying of the synthetized coupling agents.

“…Bifunctional coupling agents and chain extenders extensively used for reactive compatibilization of polycondensates, polymer blends and they may also use compatibilizer for polymer composites. 37 Epoxy-containing compounds, maleic anhydride, silane, methacrylates are preferred for compatibilization thermoplastic PET blends. It has also been reported that epoxy group containing-compounds are used as chain extenders for PBT and as compatibilizers in polyester blends.…”

This research work focused on the effects of different compatibilizers on the properties of reduced graphene oxide (rGO) reinforced poly(ethylene terephthalate) (PET)/poly(butylene terephthalate) (PBT) nanocomposites. The samples were prepared via melt compounding and injection molding methods. The Joncryl and glycidyl isooctyl polyhedral oligomeric silsesquioxane (GPOSS) were used as compatibilizers at different loading levels (0.5%-4%). The structural, thermal, mechanical, morphological, and electrical properties of the nanocomposites were investigated. The Fourier transform infrared analysis results revealed that no significant interaction was observed when GPOSS was added. On the other hand, there were more obvious changes in the peaks of the nanocomposite containing Joncryl. The thermal results showed that the compatibilizer addition caused small changes while rGO addition did not considerably affect the thermal stability of blend. The glass transition temperature of the nanocomposite significantly decreased with the addition of GPOSS. The tensile test indicated that compatibilizers improved the mechanical performance of PET/PBT/rGO nanocomposite.

“…Unfortunately, SCA in most of the published work was used as primer,7–9 and little attention is given to the role of SCA added as integral blend additive. It has been reported that bifunctional SCA as additive have found broad application in polymer modification, and they have proved to be effective chain extenders for various polycondensates and reactive compatibilizers in polymer blends 10. However, the effect of trifunctional SCA used as integral blend additive on the composites is still not understood.…”

Silane coupling agent (SCA) plays an important role in the improvement of adhesive properties of the silicone rubber (SR) sealant. In this study, three trifunctional silane coupling agents, (γ‐aminopropytriethoxysilane (APTES), (γ‐Glycidoxypropyl) methyldimethoxysilane (GDMMS), and 3‐(Trimethoxysilyl)propyl methacrylate (MPS), were used as blend additive in SR, and the effect of silane coupling agents on the properties of SR was studied. The results showed that the bond strength of samples with different combination of APTES/GDMMS, GDMMS/MPS, or APTES/MPS, was significantly improved than those of single silanes. Silanes with polar group make contribution to the bond strength increase of SR sealant. The highest bond strength value (0.53 MPa) was obtained using the combination of APTES and GDMMS. The study of the samples with (APTES and GDMMS) showed that the bond strength and tensile strength of SR increase with the increasing amount of SCA. Further increase in the SCA content makes the bond strength and tensile strength of SR sealant decrease. The increase in the amount of SCAs makes the failure modes of samples convert from adhesive failure to cohesive failure. Tack‐free time decreased linearly as the amount of SCA loading increased, while the hardness increased. It can be deduced that the trifunctional SCA has catalytic effect on the crosslinking action of SR sealant. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
