“…This can be attributed to the reinforcing effect of this nanoscale dispersed BA 25 in the PS matrix. This finding is in analogy with the results of Deshmukh et al [20] reporting that the stiffness of mica filled PVC composite changed markedly with varying particle size. Note that E r0 and E rv of the PS ternary composites were always higher than that of the PS/SBR blend.…”

Binary and ternary composites composed of polystyrene (PS), styrene-butadiene rubber (SBR), and synthetic boehmite alumina (BA) were produced by water-mediated melt compounding technique. SBR latex and/or aqueous BA suspension was injected into the molten PS in a twin-screw extruder to prepare toughened and/or reinforced polymer composites. The dispersion of the BA (two fractions with different mean particle sizes) and SBR was studied by scanning-and transmission electron microcopy techniques (SEM and TEM, respectively), and discussed. The mechanical properties of the composites were determined in static tensile, Charpy impact and short-time stress relaxation tests (performed at various temperatures). It was found that BA was mostly embedded in the SBR phase in the ternary PS/SBR/BA composite. BA incorporation increased the stiffness and tensile strength and reduced the elongation at break and impact toughness. Effect of the BA particle size was most pronounced in the tensile mechanical and stress relaxation tests. Additional incorporation of BA in the PS/SBR blend enhanced the tensile modulus and stress relaxation modulus compared to the PS/SBR blend. Relaxation master curves were constructed by applying the time-temperature superposition (TTS) principle. It was established that the inverse of the Findley power law model was fairly applicable to the stress relaxation results.

The iron compounds (iron(III) oxide-hydroxide monohydrate FeO(OH) × H 2 O, iron(III) oxide Fe 2 O 3 , and ascorbic acid) were used as oxygen scavengers modifiers in laminating of polymer films. This oxygen-scavenging system was coated on preselected films (low density polyethylene [LDPE] and polyethylene terephthalate [PET]) from which the laminates were formed. It presents the new form of composite material packaging that has the function of oxygen scavenging, which could be suitable for food packaging. The scope of the research included studies of morphology of oxygen scavengers by scanning electron microscope and their average particle size distribution measure by particle size analyzer, the effect of type, and concentration of these substances on viscosity of adhesive and seal strength of laminates.The Fourier-transform infrared spectroscopy (FTIR) of laminates was also performed to observe the potential interaction of functional groups of polyurethane adhesives with oxygen scavenger components. The most important ability of the developed system for oxygen scavenging was confirmed by measuring oxygen concentration (% vol) in a headspace with the prepared laminates. The concentrations of selected oxygen scavengers (4-6 wt%) and their combinations were studied. The most effective oxygen scavenger system integrated within the PE/PET composite film consists of 6 wt% ascorbic acid and 1 wt% FeO(OH) × H 2 O, where the oxygen concentration of 1.0 vol% (±0.20 vol%) was obtained after 15 days of storage. It was found that in this system the oxygen scavenging reaction occurs through ascorbate oxidation to dehydroascorbic acid, which is catalyzed by reduction of Fe 3+ to Fe2 + ions.

This work covers mixing of unsaturated polyester (un-polyester) with starch powders as polymer blends and study the effects of irradiation by UV-acceleration on mechanical properties of its. The unsaturated polyester was mixing by starch powders at particle size less than (45 µm) at selected weight fraction of (0, 0.5, 1, 1.5, 2, 2.5 and 3%). These properties involve ultimate tensile strength, modulus of elasticity, elongation percentage, flexural modulus, flexural strength, fracture toughness, impact strength and hardness. The results illustrate decrease in the ultimate tensile strength at and elongation percentage, while increasing modulus of elasticity, with increasing the weight ratio of starch powder to 3 % weight fraction, whereas the maximum value of hardness and flexural, impact properties happened at 1 % weight fraction for types of polymer blends.
