Various attempts have been made to overcome this drawback. For example, halogen compounds and phosphorus compounds in the polymer,
A method is known in which an inorganic flame retardant such as antimony trioxide is added if necessary. Among these methods, the method of incorporating a halogen compound is preferred because it can impart self-extinguishing properties to the polymer and the resulting flame-retardant polymer has excellent moist heat resistance.

However, in order to incorporate a halogen compound into a polymer, a method is usually adopted in which the halogen compound is added during the synthesis of the polymer or at a stage after synthesis until the molding is completed. At this time, the halogen compound is also exposed to high temperatures and decomposes, often deteriorating the quality of the molded product obtained. As a halogen compound that does not have this drawback, for example (where K, l
is a positive integer), and it has been proposed that flame retardancy can be imparted to thermoplastic polymers by blending such halogen compounds. However, the heat resistance is still insufficient, especially for polyamides, When the melting temperature is relatively high, such as polyester, there are drawbacks such as coloration occurring during mixing and a decrease in the degree of polymerization of the polymer.

As a result of intensive research on a flame retardant method for thermoplastic polyolefins that does not have such drawbacks, the present inventors have found that a specific amount of a halogen-containing bisphenylene ether or its polymer with a specific end-capped terminal as shown below is flame retardant. The present invention was achieved based on the knowledge that the above-mentioned drawbacks could be overcome by using the compound as a drug.

In particular, thread esters such as polyethylene terephthalate, polyethylene naphthalene-2,6-dicarboxylate, and polytetramethylene terephthalate have a high melting temperature, so that excellent effects can be obtained. In the flame retardant used in the present invention, the general chain group is an aryl group, which may have a non-functional substituent, and especially in the case of an aryl group substituted with a chlorine atom or a bromine atom, it is more difficult to use. This is preferable because it can improve flammability.

Further, the number of methylenes represented by n in the formula is 1 to 6, and if the number is increased beyond this value, not only is there no advantage, but the flame retardant effect is reduced, which is disadvantageous. In particular, when n is 2, it is preferable because the resulting flame-retardant polymer composition has excellent physical properties. The degree of polymerization of this bisphenylene ether represented by q in the general formula is 1 to 10, and a degree of polymerization higher than this is disadvantageous because the compatibility with the polymer decreases.

If the halogen content is less than 1% by weight, a sufficient flame retardant effect cannot be obtained, while if it is more than 20% by weight, the flame retardancy no longer improves accordingly, but rather the resulting composition. The performance may deteriorate significantly. It is advantageous. Any method can be used as the compounding method. Generally, the additives may be added and mixed at any stage during polymer synthesis or after synthesis until completion of molding. The composition of the present invention may contain, for example, titanium dioxide, risarge, various coloring pigments such as quinacridone pigments,
, copper phthalocyanine pigments, isointhrinone pigments, dioxazine pigments, pyrocholine pigments, azomethine pigments, quinolone pigments, azo pigments, benzidine pigments, etc., and also compounds such as antimony trioxide, zirconium oxide, tin oxide, etc. It may also contain or tighten. In particular, antimony trioxide is more preferred since it can improve the flame retardant performance of the obtained flame retardant polymer composition. These inorganic oxides can be kneaded with the polymer at any stage before polymer molding, but especially after crushing and kneading the polymer powder and oxide with a vibrating mill with a vibration frequency of 9 cps or more and an amplitude of 3 mm or more, the polyester can be mixed. It is preferable because the mixing and molding and dispersion state are very good and the resulting composition has excellent physical properties.
