FLAME-RESISTANT, THERMOPLASTIC POLYURETHANE ELASTOMERS, PROCESS FOR THEIR PREPARATION, AND THEIR USE Abstract of the Disclosure The invention relates to flame-resistant, thermo- plastic polyurethane elastomers containing a flame-retardant additive package comprising: a) a compound selected from the group consisting of antimony trioxide, zinc borate and mixtures thereof, b) a chlorinated polyethylene, and c) a brominated aromatic compound, preferably selected from the group consisting of polytetrabromobis(phenol)-A-glycidyl ether), pentabromophenyl ether, polytri- bromostyrene, and polytetrabromobis- (phenol)-A-carbonate). The flame-retardant additive package may be incorporated into the starting components used to prepare the thermoplastic polyurethane prior to the reaction which forms the polyurethane, to the reaction mixture during the reaction, or to the finished thermoplastic polyurethane elastomers. The flame-resistant, thermoplastic polyurethane elastomers are suitable for the preparation of, for example, molded articles, films, sheets, and cable jackets.
