FIELD: chemistry.
SUBSTANCE: flame-extinguishing polymer composition contains a combustible polymer mixed with a bromated flame-extinguishing additive selected from one or more compounds given below: (i) a copolymer containing styrene and 2,3-dibromopropylmaleimide repeating units; (ii) a bromated polyester containing bromine atoms bonded with aliphatic groups; (iii) an allyl ether which is bromated on a novolac resin ring; (iv) 3-bromo-2-hydroxypropyl ether of novolac resin; (v) 2,3-dibromopropyl ether cresol-novolac resin, and (vi) a bromated polymer or a copolymer obtained via ROMP.
EFFECT: stability of the flame-extinguishing additive at high temperatures, low toxicity and avoiding significant loss of physical properties of the polymer during use thereof.
