FIELD: chemistry.
SUBSTANCE: described is self-extinguishing foamed polystyrene with low content of bromated antipyrene, obtained from pre-foamed or foaming styrene polymer which contains bromated antipyrene and a phosphorus compound, characterised by that the phosphorus compound is a product of the reaction of mono- or diammonium phosphate with urea, taken in ratio phosphate: urea equal to (1.0-2.3) - (1-3), respectively, with the following ratio of components (pts. wt): styrene polymer 100, bromated antipyrene 1.0-1.5, product of reacting mono- and diammonium phosphate with urea 4.0-8.0.
EFFECT: endowing self-extinguishing polystyrene with higher fire resistance with low content of antipyrene.
