“…27,28 Studies in this group are very limited compared with the other two groups, because it is believed that the general-purpose polymers cannot tolerate the high temperature process required for blending with PPS. Chen et al 24 studied blends composed of PPS and polyethylene at various component ratios and described the relationship between the domain size and the composition.…”

“…For example, Masamoto et al 27 first reacted PPS with a diisocyanate derivative and then blended the so-modified PPS with ethylene copolymer containing ca 2 wt% of maleic anhydride. They reported that energy dissipation by matrix yielding enhances the notched Izod impact strength of the (80/20) PPS/ethylene copolymer by 50 times compared with that of pristine PPS.…”

Poly(p-phenylene sulfide) (PPS) is a high performance polymer that has superior chemical resistance and heat stability, but its brittleness is a serious drawback for applications. The objective of this work is to improve the physical properties of PPS by incorporating a small amount of either poly(ethylene-ran-methylacrylate-ran-glycidyl methacrylate) (EMA-GMA) or poly(ethyleneran-glycidyl methacrylate)-graft-poly(methyl methacrylate) (EGMA-g-PMMA) by melt mixing under a high shear rate. It was demonstrated that the chemical reaction between PPS and EMA-GMA (or EGMA-g-PMMA) proceeded efficiently at the interface and that the domains of EMA-GMA (or EGMA-g-PMMA) were finely dispersed in the PSS matrix with size of ca 0.1-0.3 lm. The resultant copolymers formed at the interface contributed to a decrease in the interfacial tension and an increase in the interfacial adhesion so that the obtained PPS/EMA-GMA blends (or PPS/EGMA-g-PMMA blends) showed excellent mechanical properties, at the same time retaining high thermal stability. Polymer Journal ( , good electrical and electronic properties, good mold precision, and high stiffness and modulus (tensile modulus¼2600-3900 MPa). 1 The semi-crystalline PPS has a T g of 88-93 1C, T m of 280-285 1C and an equilibrium melting point of its orthorhombic crystals at 303-350 1C. 1-3 Furthermore, PPS shows extraordinary flame retardance, having a limited oxygen index of 44%, which belongs to the highest group among polymeric materials together with poly(vinyl chloride) and polyimide. 4 So taking advantage of these unique properties, PPS has been applied as an alternative material for metals and thermoset polymers; for example, automobile parts and electrical and electronics parts. 1 However, its low toughness and high brittleness, which originate from its rigid structure, are serious drawbacks, preventing further applications.Thus, in order to improve the properties of PPS, blending of PPS has been intensively studied, and can be categorized into three groups. The first group of PPS blends are formed with other high performance super-engineering plastics, such as polysulfone, 5 poly(ether sulfone) (PES) 6,7 and liquid crystalline polymers (LCPs), 8-10 which have thermal stability over 150 1C for long durations. It is reported that PPS blends having an amorphous polysulfone matrix (p50 wt% of PPS) show good tensile properties, but that blends having a PPS matrix (450 wt% of PPS) become brittle. 5 It was found that PPS and PES are partially miscible, in which PES is also an amorphous polymer having excellent mechanical properties. 6 Although mechanical proper-

“…However, our former study for the toughened PPS from the PPS/elastomer alloy system suggested that, to obtain the toughened PPS, the elastomer particle should be below 0.4 lm. [6] Considering this fact, a more finely dispersed PPE in the PPS matrix may be desired.…”

A poly(phenylene sulfide) (PPS)-based nanocomposite (PPSNC) filled with titanate layers was used as a matrix polymer in a PPS/maleic anhydride ethylene butadiene co-polymer (MA-EBR) blend. The toughness of the PPS was increased significantly, because the inorganic titanate layers behaved as an effective compatibilizer to enhance the blending effect of MA-EBR. Scanning electron microscopy analysis confirmed that MA-EBR domains were finer and uniformly dispersed with a small particle size in the PPS matrix. In addition, transmission electron microscopy analysis proved that titanate layers aggregated at the interface between the PPS and MA-EBR. On the other hand, the initial morphology of the titanate layer in the PPSNC was maintained when untreated EBR was used as the domain polymer. The morphologies of titanate layers in the three types of polymers blended with this nanocomposite technique, including PPSNC/PA6, were investigated to discuss the factor which titanate layers affect the morphology of domain polymers, and it was indicated that the behavior of titanate layers was governed by an affinity between polymers and titanate layer surface.
