<p>Flame-resistant fibres of linear, thermoplastic polyesters Linear, thermoplastic polyesters based on terephthalic acid, ethylene glycol or 1,4-butanediol, which contain co-condensed chlorinated and/or brominated 1,3-bis-(hydroxyalkyl)-benzimi-dazolones, crystallise on stretching and are suitable for the manufacture of flame-resistant to flameproof fibres.</p> |
