摘要: Flameproofing of aromatic polymers is achieved by adding a synergistic combination of (a) a phosphorus compound and (b) a compound of formula R(CH.sub.2 X).sub.n, wherein R is an aromatic or heterocyclic residue, X is a leaving group and n is at least 2. Preferred phosphorus compounds are esters of phosphoric acid. The flameproofed polymers may contain aromatic groups in the main chain or as side-groups, for instance styrene polymers and copolymers, aromatic polyesters, polycarbonates and polyphenylene oxides.
