  The present invention provides a phosphate-phosphonate compound which has a low volatility and a high phosphorus content, does not exert adverse influences on the physical properties of a product containing the phosphate-phosphonate compound as a material, and is recyclable and causes substantially no environmental load since a halogen atom such as a chlorine atom or a bromine atom is not included. A phosphorus compound containing a phosphate-phosphonate bond in one molecule and having a specific structure has a high flame retarding property. By using a phosphate-phosphonate compound as a flame retarding agent for a polyurethane or for a polyester, preferable plasticity and flame retarding property are obtained. Such a flame retardant agent exerts substantially no adverse influences on the physical properties of a polyurethane foam or a polyester fiber.

  本发明提供了一种磷酸酯-膦酸盐化合物，其挥发性低、磷含量高，不会对含有该磷酸酯-膦酸盐化合物作为材料的产品的物理性能产生不良影响，而且可回收利用，因为不含有氯或溴等卤素原子，所以几乎不会对环境造成负担。具有特定结构的含有磷酸酯-膦酸盐键的磷化合物具有高阻燃性能。通过将磷酸酯-膦酸盐化合物用作聚氨酯或聚酯的阻燃剂，可以获得理想的可塑性和阻燃性能。这种阻燃剂几乎不会对聚氨酯泡沫或聚酯纤维的物理性能产生不良影响。

  A wholly aromatic polyester composition comprising (a) 100 parts by weight of a wholly aromatic polyester containing as a main component at least one compound selected from the group consisting of aromatic dicarboxylic acids, aromatic dihydroxy compounds and aromatic hydroxycarboxylic acids, and (b) from 5 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the wholly aromatic polyester and having a boiling point of at least about 200°C under atmospheric pressure and a molecular weight of not more than 1.000. The wholly aromatic polyester composition is produced advantageously by polycondensing in the molten state the polyester-forming starting mixture in the presence of the low-molecular-weight compound. A film-like or fibrous article of a wholly aromatic polyester may be produced by extracting the low-molecular-weight compound from a film-like or fibrous article of the wholly aromatic polyester composition.

  全芳香族聚酯组合物，包括 (a) 100 份（按重量计）全芳香族聚酯，其主要成分含有至少一种选自芳香族二 羧酸、芳香族二羟基化合物和芳香族羟基羧酸的化合物，以及 (b) 5 至 300 重量份的低分子量化合物，该化合物与全芳香族聚酯基本不发生 反应，在常压下沸点至少约为 200℃，分子量不超过 1.000。 全芳香族聚酯组合物的有利生产方法是在低分子量化合物存在下，在熔融状态下对聚酯形成起始混合物进行缩聚。 全芳香族聚酯的薄膜状或纤维状制品可通过从全芳香族聚酯组合物的薄膜状或纤维状制品中提取低分子量化合物而制成。
