    • The fire retardancy of polyesters is enhanced with halophenoxyphosphazenes that contain a P--O--P bond. Preferred materials are reaction products of a halogenated phenol and a phosphonitrilic halide. Brominated phenols are preferred although chlorophenols can be used. Of the brominated phenols, preferred starting materials are p-bromophenol, 2,4-dibromophenol and mixtures thereof. Phosphonitrilic chlorides are preferred starting materials. Pure phosphonitrilic halides can be used; however, phosphonitrilic halide mixtures are preferred because of their availability. Cyclic and linear phosphonitrilic halides are useful as well as mixtures thereof. Saturated and unsaturated polyesters can be made fire retardant by this invention, as can thermoplastic and thermosetting materials. Linear and crosslinked polyesters can be treated. Preferred polyesters are fiber-forming polyesters of a diol and dibasic acid, such as poly(ethylene terephthalate) and poly(1,4-cyclohexylenedimethyleneterephthalate).
    • 使用含有P-O-P键的卤代苯氧基磷腈可以提高聚酯的阻燃性。 优选的材料是卤代苯酚和膦酰基卤化物的反应产物。 尽管可以使用氯酚,但优选溴化酚。 在溴化酚中,优选的原料是对溴苯酚,2,4-二溴苯酚及其混合物。 次膦酸氯化物是优选的原料。 可以使用纯的三氯化鏻; 然而,由于它们的可用性,优选膦酰氯化物混合物。 环状和线性的膦酰氯化物是有用的,以及它们的混合物。 饱和和不饱和聚酯可以通过本发明制成阻燃剂,如热塑性和热固性材料。 可以处理线性和交联的聚酯。 优选的聚酯是二醇和二元酸的成纤聚酯,例如聚(对苯二甲酸乙二醇酯)和聚(1,4-环己烯二甲基对苯二甲酸酯)。
