“…Mg(OH) 2 acts as a FR with excellent smoke suppression ability 9. Therefore, the addition of Mg(OH) 2 as a secondary FR may reduce the amount of PBBA required to meet FR demands 10, 11. Although the addition of PBBA imparts FR properties to the PP composite and possibly improves its compatibility as discussed above, it also affects adversely the mechanical properties of the composite.…”

Pentabromobenzylacrylate (PBBA) is a possible candidate for use as a fire retardant (FR) in polypropylene (PP) composites. While PBBA imparts FR properties to the PP composite, it also affects adversely its mechanical properties. The FR may undergo thermal polymerization or grafting to the PP chains during processing. To study the effect of the different forms of FR (monomer, polymerized, or grafted) on composite properties, we have quantified the extent of FR polymerization and extent of grafting onto the PP chains. Fourier transform infrared microscopy was used in this work to determine the extent of polymerization and the spatial distribution of the FR. The latter was found to be homogeneous throughout the composite. Thermal polymerization of the FR during extrusion is varied mainly by the addition of an antioxidant. The grafting process of the FR onto PP depends on the degree of thermal polymerization, and therefore on the addition of antioxidant. The limiting value for grafting achieved at full polymerization is ϳ10% w/w. The grafted FR was found to have a significant effect on PP crystallinity, and hence it is expected to affect the mechanical properties as well. Bromine analysis indicates the FR has reacted with filler surfaces as well.

“…Since water is indispensable to various human activities, much attention has been paid to securing clean water sources. One of the recent problems is pollution by toxic organic compounds such as 2,2',3,3',4,4',5,5',6,6'-bromdiphenyl ether [1,2,3] . 2,2',3,3',4,4',5,5',6,6'-bromdiphenyl ether is a common solvent and an intermediate in organic synthesis, and agricultural and pharmaceutical synthetic pathways [4,5] .…”

2,2',3,3',4,4',5,5',6,6'-bromdiphenyl ether (BDE-209) solutions were irradiated with ultraviolet (UV) and electron beams. Organic compounds were fully removed by each type of radiation. The absorbed energy of the ionizing radiation (electron beams) needed for removal was much lower than that of UV photocatalysis. BDE-209 removal using the ionizing radiation was accelerated drastically by dosage. It is suggested that pH value of solution affect the decomposition rates. Radiolysis with the high pH value showed consistently high rate and high efficiency of BDE-209 removal.

Single-faced flame resistance of cotton fabrics modifiedviamist copolymerization

Cotton fabrics with single-faced flame resistance are successfully fabricated through a simple mist copolymerization process using pentabromobenzyl acrylate (PBBA) as the functional monomer. The comonomers are methyl acrylate (MA), which can react with the hydroxyl groups of cellulose by transesterification, and divinyl benzene (DVB), a cross-linker. SEM images indicate that a very thin copolymer layer (the thickness is about 200 nm) was formed on the cotton fiber surface and the flame resistance tests show that the modified fabrics have an improved flammability with longer time to ignition (TTI), lower peak heat release rate (PHRR), lower total heat release (THR), and lower average mass loss rate (AMLR), when compared to the original cotton fabric. The modification also results in good wearing durability because the flame-retardant coating was covalently linked to the cotton fabric surface by many ester groups. Moreover, desired cotton characteristics such as tensile strength, water absorbency, vapor permeability and flexibility are mostly retained because the mist method gives a single-faced modification of the cotton fabrics.
