“…It was demonstrated that the so-compatibilized interface in PPS/LCP blends significantly contributes to the enhancement of tensile properties and impact strength. 10 The second group of PPS blends is formed with conventional engineering plastics with thermal stability between 100-140 1C for long usage such as crystalline polyamide (PA) [11][12][13] and poly(ethylene terephthalate) (PET), [14][15][16] and amorphous poly(phenylene ether) 17 and polycarbonate (PC). 18 It is reported that (20/80) PPS/PA4,6 (T m of PA4,6¼295 1C) blends have a miscible region, which appears under a high shear rate at 310-320 1C 13 although the solubility parameter of PPS is extremely high (12.5 (cal cm À3 ) 0.5 ) compared with other polymers and this makes it difficult for PPS to have miscibility with other polymers.…”

“…Furthermore, in a study of PPS/PET blends in the presence of pre-made PPS-graft-PET copolymer it was found that the presence of the PPS matrix increased the crystallization temperature of PET domains, in which the magnitude of the increase in the PET crystallization temperature coincided with the viscosity ratio and the extent of solubilization of PPS homopolymer into the graft copolymer. 15 In PPS/PC blends, as inherently high interfacial tension would result in an unstable interface, 23 a small amount of epoxy resin was added to the PPS/PC blends. In this system it is surmised that the epoxy resin reacts with the hydroxyl group located at the PC chain ends, which is generated by hydrolysis of PC during melt blending.…”

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-

The morphology and nonisothermal crystallization behavior of blends made of poly(phenylene sulfide) (PPS), with a amorphous polycarbonate (PC) were studied. The blend is found to be partially miscible by the dynamic mechanical thermal analysis (DMTA) and melt rheological measurements. The nonisothermal crystallization behavior of blend was studied by differential scanning calorimetry (DSC). The results show clearly that the crystallization temperatures of PPS component in the blend decrease with increasing of PC contents. The crystallization kinetics was then analyzed by Avrami, Jeziorny, and Ozawa methods. It can be concluded that the addition of PC decreases the PPS overall crystallization rate because of the higher viscosity of PC and/or partial miscibility of blend, despite of small heterogeneous nucleation effect by the PC phase and/or phase interface. The results of the activation energy obtained by Kissinger method further confirm that the amorphous PC in the partial miscible PPS/PC blend may act as a crystallization inhibitor of PPS.

Poly(phenylene sulfide)/ferrosoferric oxide composites (PPS/Fe 3 O 4 ) with various loading levels were prepared by melt compounding. The microstructure of composites was investigated using SEM and XRD. The rheological, electrical and magnetic properties were characterized respectively by the parallel plate rheometer, high resistance meter, and magnetometer. The results reveal that the Fe 3 O 4 particles are well dispersed in the PPS matrix due to their nice affinity, which results in a weak strain overshoot at large amplitude oscillatory level. Both the rheological and the electrical responses of the composites show a typical percolation behavior. But the rheological percolation presents lower threshold (< 40 wt %) than that of electrical percolation ($ 50 wt %), which is attributed to the difference structure of the percolation network. The magnetic response, however, shows good linear relation with Fe 3 O 4 loadings, indicating that the physical percolation has little influence on the magnetic properties. This is mainly due to the yielded long-range magnetic interactions among Fe 3 O 4 particles in the applied field, which are far stronger than those nonmagnetic physical interactions accounting for percolation.
