The mechanical performance of immiscible blends of poly(2,6-dimethyl-1,4-phenylene ether) (PPE) and poly(styrene-co-acrylonitrile) (SAN) and the subsequent influence of compatibilisation by tailored polystyrene-block-polybutadiene-block-poly(methyl methacrylate) triblock terpolymers (SBM) on the mechanical performance under static and dynamic loads is analysed in detail. A PPE/SAN 60/40 blend was selected as a base system for the compatibilisation experiments. The observed static tensile behaviour is described by micromechanical models and correlated to the blend microstructures as observed by transmission electron microscopy. In most cases, the addition of the SBM triblock terpolymers further enhances the ductility of the blend while only leading to a minor reduction of modulus and strength. Triblock terpolymers with symmetric end blocks, mainly located at the interface between PPE and SAN, led to nearly isotropic specimens. In contrast, SBM materials with a longer polystyrene block predominantly formed micelles in the PPE phase and the blends revealed a highly anisotropic morphology. Comparative investigations of the fatigue crack growth behaviour parallel to the direction of injection also reflected this variation in mechanical anisotropy of the compatibilised blends. A poor toughness and a predominant interfacial failure were observed in the case of the SBM with a long polystyrene block. In contrast, a considerable improvement in properties as a result of pronounced plastic deformations was observed for blends compatibilised by triblock terpolymers with symmetric end blocks. The systematic correlation between morphology and mechanical performance of compatibilised PPE/SAN blends established in this study provides an efficient way for the desired selection of suitable and effective compatibilising agents, ensuring both a superior multiaxial toughness as well as a high strength and modulus of the overall system.

“…Due to the sufficiently fine phase structure in binary blend, that is, practically no change in the particle size (especially for PEGMA), a favorable mutual influence of rigid and elastomeric inclusions seems to be the dominant effect. The explanation could be the enhanced ability of elastomer particles to cavitate due to the simultaneous existence of a stress field developed by rigid particles and having just the opposite character 16 (to that of the elastomer particles), that is, compressive. On the other hand, cavitation of these very small (and, in the case of PE-GMA, also relatively rigid) particles is not very probable (so far, experimental verification or excluding the cavitation of particles of the size around 100 nm in our blends has been without success).…”

A ternary blend of the PA6 matrix with a finely dispersed rigid polymer and elastomer is a system with well-balanced mechanical properties. Its micromechanical behavior, especially that of the elastomer phase, apparently differs from corresponding binary mixtures. This study shows the influence of the elastomer type, modulus, and reactivity on the behavior of ternary blends in comparison with analogous binary PA6/elastomer combinations. The presence of rigid reactive poly(styrene-co-maleic anhydride) (SMA) enhanced the properties of all the systems studied. For nonreactive elastomers, the dominant effect was refinement of their size due to enhanced viscosity, whereas for functionalized low-modulus elastomers, the very good balance of properties was due to synergistic influences of both finely dispersed phases. Of interest is the enhanced toughness of ternary blends also for more rigid elastomers having a low toughening efficiency in binary blends. An appropriate addition of rigid SMA together with an elastomer enhances the energy absorption of the matrix, probably without cavitation of very small elastomer particles. Of importance also is the simultaneous strain-hardening effect of deformed rigid particles.

The stress-strain behavior of metal-filled polymeric composites was studied at various tensile deformation rates. The dependency of the mechanical properties of iron-epoxy composites, such as elastic modulus, maximum load, breaking-strain and breaking-energy, on the rate of deformation, as well as on the filler-volume fraction was examined. The results corroborate satisfactorily the theoretically predicted values.
