“…[7] A similar reaction may have occurred between the MDI-treated PPS and maleic anhydridemodified PPE. The isocyanate group of MDI will react with 1SH of the PPS end-group to form 1SCONH1 [10] and, furthermore, this group may be assumed to be bonded with polycarbodiimide.…”

“…We confirmed the disappearance of this carbodiimide absorbance in the reactive processing of MDI-treated PPS with the elastomer having the functional group of maleic anhydride. [7] During the reactive processing, the carbonyl band of the anhydride group was also confirmed to have disappeared. [7] This implies a chemical reaction between the carbodiimide group and the maleic anhydride group.…”

“…[7] This implies a chemical reaction between the carbodiimide group and the maleic anhydride group. [7] Thus, in the case of reactive processing of MDI-treated PPS with maleic anhydride-modified PPE, a similar chemical reaction between the carbodiimide group and the maleic anhydride group may occur. Thus, chemical bonding between PPS and PPE may be generated.…”

“…However, the large brittleness and weak toughness of PPS confine its high‐end applications. To overcome these deficiencies, modification of PPS with elastomers, inorganic particles, glass fiber or carbon fiber by melt blending developed rapidly in recent years and showed remarkable reinforcing effects on the mechanical, thermal, and wear properties. These toughening methods are based on different conventional toughening mechanism, such as elastomers toughening theory, cold drawing concept, crazing theory and shear band/crazing interaction theory .…”

In order to improve the impact strength of PPS‐based strontium ferrite composite, the thermoplastic polyurethane (TPU) elastomer was added in the composite as a toughening agent. The composites were obtained by melt‐blending PPS, TPU and strontium ferrites in twin‐screw extruder. The crystalline state, thermal property, surface morphology and impact strength of the composites were investigated by using X‐ray diffraction, differential scanning calorimetry, thermoravimetric analysis, scanning electron microscope and izod impact test. The addition of TPU improves impact strength of PPS‐based strontium ferrite composite. When the addition of TPU increases to 11wt %, the impact strength of Sr‐ferrite/PPS/TPU composite is enhanced by 51.44% compared with the sample without TPU addition, and reaches to 5.77 kJ/m2. The occurrence of bonding interaction between PPS and TPU, demonstrated by a series of experiments, changes the structure and impact properties of PPS. Based on the experimental results, a possible mechanism is proposed to explain the improvement of Sr‐ferrite/PPS/TPU composites, which is different from the conventional toughening mechanism by the conformation of elastomers and the suppression of microcracks propagation. © 2016 Wiley Periodicals, Inc.

“…13 A disadvantage of this modification with low-modulus elastomer is the sharp decrease in tensile strength of the blends. 4,[7][8][9][10]14 This invites the investigation of introducing ductile thermoplastics such as HDPE, PC, and nylon 6 into the elastomer-toughened polymer blends. 14,15 The recent research involving PPS/PA66 blends was mainly focused on their tribological properties when filling with polytetrafluoroethylene (PTFE) and glass fibre.…”

In this study, styrene-b-ethylene/butylene-bstyrene triblock copolymer (SEBS) and maleic anhydride grafted SEBS (SEBS-g-MA) were used as compatibilizers for the blends of polyphenylene sulfide/nylon 66 (PPS/PA66). The mechanical properties, including impact and tensile properties and morphology of the blends, were investigated by mechanical properties measurements and scanning electron microscopy. Impact measurements indicated that the impact strength of the blends increases slowly with elastomer (SEBS and SEBS-g-MA) content upto 20 wt %; thereafter, it increases sharply with increasing elastomer content. The impact energy of the elastomer-compatibilized PPS/ PA66 blends exceeded that of pure nylon 66, implying that the nylon 66 can be further toughened by the incorporation of brittle PPS minor phase in the presence of SEBS or SEBSg-MA. The compatibilization efficiency of SEBS-g-MA for nylon-rich PPS/PA66 was found to be higher than SEBS due to the in situ forming SEBS interphase between PPS and nylon 66. The correlation between the impact property and morphology of the SEBS-g-MA compatibilized PPS/ PA66 blends is discussed. The excellent impact strength of the nylon-rich blends resulted from shield yielding of the matrix.
