“…The incorporation of halogen‐containing additives has been reported to have a good flame retardant effect on PS resins, 7–9 and brominated flame‐retardants for PS, such as tetrabromoethane and hexabromocyclododecane, are commercially available. However, because concerns about the effects of these halogenated additives on the environment and on human health have been raised, research aimed at developing effective halogen‐free flame‐retardants has been increasing 10,11 …”

We synthesized an acrylic acid 4-[(10-oxo-10H-9-oxa-10λ5-phospaphenanthren-10-yl)-phenylamino-methyl]-phenyl ester (DOPO-AC), a novel Schiff base derivative based on 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, and evaluated its utility as a flame retardant for polystyrene (PS). The synthesized DOPO-AC was characterized by Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance spectroscopy, and high-resolution mass spectrometry. The reactive vinyl groups of DOPO-AC further copolymerized with styrene to produce PS/DOPO-AC. Thermogravimetric analysis showed that DOPO-AC could clearly improve the char residue formation. By comparing the data of T 5% and T 10% , it was found that the thermal stability of the PS/DOPO-AC copolymer was reduced. We investigated the influence of DOPO-AC on the flame retardancy of PS by determining limiting oxygen indexes, conducting vertical burning tests (UL-94), and carrying out thermogravimetry combined with differential thermal analysis. These results revealed that PS containing 5 wt% DOPO-AC had a UL-94V-0 rating and a limiting oxygen index of 29.6%. Residues of PS/DOPO-AC copolymer after the UL-94V tests were analyzed by scanning electron microscopy, X-ray photoelectron spectroscopy, and FTIR spectroscopy; and the results allowed us to propose a flame retardant mechanism for PS/DOPO-AC copolymer. Taken together, our results prove that DOPO-AC is an effective flame retardant for PS.

“…Common additivetype flame retardants are the halogenated aliphatics, brominated aromatics, halogenated and nonhalogenated organophosphates, and the oxides of aluminum and antimony. [3][4][5][6][7][8][9][10] The use of halogen-based flame retardant is now being limited because of the serious environmental issues they present and they are being replaced by halogen-free flame retardants. This paper aims to study the mechanical properties of halogen-free intumescent flame-retardant ABS composites.…”

The effect of an ultrahigh rubber acrylonitrile-butadiene-styrene (ABS) impact modifier resin (UHR-ABS) on the mechanical properties of an intumescent flame-retardant ABS composite was characterized. Samples were obtained by compounding ABS and an intumescent flame-retardant master batch that was prepared using an intumescent flame-retardant composite (IFRC) with ABS and/or UHR-ABS as well as by direct compounding IFRC, UHR-ABS, and ABS. The incorporation of UHR-ABS resulted in reduction in the storage modulus, damping behavior and glass transition temperature, as evidenced by dynamic mechanical analysis. With increasing mass fraction of the UHR-ABS, the tensile strength and the flexural strength decreased gradually, and the notched impact strength increased, but the increase was more significant for compounding IFRC, UHR-ABS, and ABS than for compounding ABS and IFRC master batches.SEM micrographs of the fresh fracture surface of the composites were used to estimate the mechanism of the increased notched impact strength owing to the incorporation of UHR-ABS.
