Summary: The flame retardant mechanisms of red phosphorus, magnesium hydroxide and red phosphorus combined with magnesium hydroxide were studied in high impact polystyrene by means of comprehensive decomposition studies and combustion tests. The study is intended to illuminate prerequisites and the potential...
Mechanism of flameretardant action of red phosphorus in polyacrylonitrile. BALLISTRERI A,MONTAUDO G,PUGLISI C, et al. Journal of Polymer Science:Polymer Chemistry Edition . 1983Ballistreri, A.; Montaudo, G.; Puglisi, C.; Scamporrino, E.; Vitalini, D.; Calgari, S. Mechanism of Flame-...
The mechanism of flame retardant (FR) action of red phosphorus in polyacrylonitrile combustion was investigated by thermogravimetry, flash-pyrolysis GC-MS, and combustion methods. Red phosphorus was found to increase the thermal stability in air of polyacrylonitrile and to induce a char residue incremen...
The flame-retardation mechanism of organic phosphorus compounds has been sum-marized in some monographs [2–4].3.1 The flame-retardation mode in condensed phaseNo matter whether it is flame-retardant thermoplasticity or thermosetting polymers,the main function of phosphorus flame retardants is not in...
Novel phosphrous flame retardant tetramethylene bis(orthophosphorylurea) (TBPU) was synthesized by the reaction of diphosphoric acid with 1,4-butanediol and urea, and charaterized by Fourier transform infrared spectroscopy (FT-IR). As the amount of TBPU added in polyurethane foam (PUF) was in...
A novel flame retardant containing phosphorus was synthesized from hydroxyethyl methacrylate(1),phosphorus oxychloride(2) and methanol.The structure was characterized by 1H NMR and IR.The optimal reaction conditions at 0 ℃ for 6 h was as follows: 1 was 0.5 mol,n(1) :n(2) was 1.0 :1.3.关...

The flame-retardant mechanism of PNSFR in TPU was also disclosed using thermogravimetric analysis (TG), scanning electron micrograph, TG-infared spectrometry, and Fourier transform infrared spectroscopy. The sulfur and phosphorus elements of PNSFR can be kept in residual char. Moreover, an optimal ...
