“…However, when the grafting ratio of POE-g-SAN increased higher than about 30.0%, the Notched Izod impact strength did not increase anymore. A similar result had been reported by Wang X.D et al, 12 which showed that further increasing of graft ratio of MA result in a decrease of the impact strength of PPO/PA6/POE-g-MA blend. Figure 12 shows the effect of POE content on the Notched Izod impact strength and tensile strength of SAN/POE-g-SAN blends.…”

Metallocene-Based Polyethylene-Octene-graft-styrene/acrylonitrile (POE-g-SAN) was synthesized by grafting styrene (St) and acrylonitrile (An) onto POE elastomer. The reaction was carried out in toluene using benzoyl peroxide as initiator at 75 C. Various weight ratios of monomers, weight ratios of POE to monomers, initiator concentration, reactant concentration, and reaction time were studied to investigate their effects on the graft copolymerization. The graft copolymer were identified and characterized by FT/IR spectroscopy and 1 H NMR. The chain structure of the graft copolymer was investigated by glass transition temperature using differential scanning calorimetry (DSC). The results showed that St/An was grafted on the POE chains, and the graft branches effected the crystallization of POE chains and made the melt temperature and the fusion heat be lower. In addition, according to the research on mechanical properties of the SAN/POE-g-SAN blend, a remarkable toughening effect of POE-g-SAN on SAN resin was found. By means of scanning electron microscopy (SEM), the toughening mechanism is proposed to be crazing initiation from rubber particles and shear deformation of SAN matrix.

“…During the last decade, extensive research has been carried out in areas of compatibilization of the nylon/ PPO blends [11][12][13][14][15][16][17][18]. Blends of a PPO/PA6 alloy toughened with a novel polyolefin elastomer, poly(ethylene-1-octene) (POE), were prepared via melt extrusion [6].…”

The properties of polyamide 6 (PA6)/poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) blends (60/40, wt%) compatibilized by poly(styrene-co-maleic anhydride) (SMA) were studied. The addition of SMA can form an in situ copolymer, SMA-graft-PA6. The SMA-graft-PA6 copolymer actually plays a key role as a compatibilizer to improve the interface between PA6 and PPO. It was found that the effect of compatibilization resulted in improvement of the morphology, impact strength and water absorbability of PA6/PPO blends (60/40, wt%), but with no favorable effects for thermal stability. However, at high SMA contents, the properties of PA6/PPO (60/40, wt%) blends deteriorated to some degree.

“…[3][4][5][6][7] Due to the higher adhesion with PPO/PA6 matrix, the modified elastomers had better toughening effects than the elastomers without modification, i.e., maleated poly (ethylene-1-octene) elastomer (POE-g-MA) versus POE and maleated ethylene-propylene-diene-monomer rubber (EPDM-g-MA) versus EPDM. [8][9][10] On the other hand, the morphology of elastomers significantly influenced the toughening effect on the PPO/PA6 blends. It was reported that the network of maleated styrene-ethylene-butylenestyrene copolymer (SEBS-g-MA) domain was more effective in stopping the growth of the crazing and shear yields than the individual particles in the PPO/ PA6 blends.…”

Poly(2,6-dimethyl-1,4-phenylene oxide)/ polyamide 6 (PPO/PA6 30/70) blends were impact modified by addition of three kinds of maleated polystyrene-based copolymers, i.e., maleated styrene-ethylene-butylene-styrene copolymer (SEBS-g-MA), maleated methyl methacrylate-butadiene-styrene copolymer (MBS-g-MA), and maleated acrylonitrile-butadiene-styrene copolymer (ABS-g-MA). The mechanical properties, morphology and rheological behavior of the impact modified PPO/PA6 blends were investigated. The selective location of the maleated copolymers in one phase or at interface accounted for the different toughening effects of the maleated copolymer, which is closely related to their molecular structure and composition. SEBS-g-MA was uniformly dispersed in PPO phase and greatly toughened PPO/PA6 blends even at low temperature. MBS-g-MA particles were mainly dispersed in the PA6 phase and around the PPO phase, resulting in a significant enhancement of the notched Izod impact strength of PPO/PA6 blends from 45 J/m to 281 J/m at the MBS-g-MA content of 20 phr. In comparison, the ABS-g-MA was mainly dispersed in PA6 phase without much influencing the original mechanical properties of the PPO/PA6 blend. The different molecule structure and selective location of the maleated copolymers in the blends were reflected by the change of rheological behavior as well.
