Certain brominated polymers compounds are effective FR additives for combustible organic polymers. These FR additives include: i) a copolymer having styrene and 2,3-dibromopropylmaleimide repeating units; ii) a brominated polyester having aliphatically bound bromine; iii) an allyl ether of a ring-brominated novolac resin; iv) a 3-bromo- 2-hydroxypropyl ether of a novolac resin; v) a 2,3-dibromopropyl ether of a cresol novolac resin; and vi) a brominated ROMP polymer or copolymer. Certains composés de polymères bromés constituent defficaces additifs ignifuges pour polymères organiques combustibles. Ces additifs ignifuges comprennent : i) un copolymère comportant des motifs répétitifs de styrène et de 2,3-dibromopropylmaléimide; ii) un polyester bromé contenant du brome à liaison aliphatique; iii) un éther allylique de résine novolaque à cycle bromé; iv) un éther 3-bromo-2-hydroxypropylique dune résine novolaque; v) un éther 2,3-dibromopropylique de résine crésol novolaque; et vi) un polymère ou copolymère ROMP bromé.
