チモンの代りに三酸化ゲルマニウムが好んで用いられて
いる。As food packaging containers, polyethylene terephthalate is excellent in terms of food hygiene because it does not require the use of plasticizers like polyvinyl chloride and does not leave behind harmful monomers like polyacrylonitrile. In order to make the material as transparent as glass, the catalyst is selected to have good solubility in the polymer. For example, germanium trioxide is preferably used as a polymerization catalyst in place of antimony trioxide, which is widely used for fibers, films, industrial resins, and the like.

衛生上問題がある。For hue, it is known to use a toning agent such as a cobalt compound (for example, JP-A-57165424).
However, cobalt compounds tend to impair the thermal stability of polymers, and there is a risk that cobalt compounds may be eluted, albeit in small amounts, into acidic food liquids. Similarly, copper phthalocyanine-based dyes are hygienic.

(1)重合初期に高温常圧保持時間を通常より長目にと
る。In the present invention, 0.9 to 2.2% by weight of diethylene glycol is produced as a by-product during the polyester reaction. When producing polyester, the residual rate in the polymer is 0.9~
Do not add diethylene glycol to 2.2% by weight. When added, a small amount of unreacted diethylene glycol remains, which poses a hygiene problem. Therefore,
Diethylene glycol must be produced as a by-product in such a way that it can be copolymerized during the reaction. As a specific method, for example, (1) the holding time at high temperature and normal pressure is set longer than usual in the initial stage of polymerization.
(2) エステル化又はエステル交換反応終了後、リ

これによってポリマーが熱的に不安定となる。0.9〜
2.2重量%の範囲にある限り、熱安定性と流動性のバ
ランスがとれ、良好な成形品が得られる。The amount of diethylene glycol copolymerized as a by-product is 0.9 to 2.2% by weight based on the polyester. If it is less than 0.9% by weight, it is necessary to increase the melt molding temperature and thermal decomposition is likely to occur. If the molding temperature is not raised, the high viscosity will cause shear heat generation during melting, which will cause the polymer to deteriorate. If it exceeds 2.2% by weight, the molding temperature can be lowered, but too many ether bonds enter the main chain,
This makes the polymer thermally unstable. 0.9~
As long as the content is within the range of 2.2% by weight, thermal stability and fluidity are well balanced and good molded products can be obtained.
本発明において、更に重合初期以前にアントラキノン系
ブルー染料を0,05〜2.0ppm添加する。In the present invention, 0.05 to 2.0 ppm of anthraquinone blue dye is further added before the initial stage of polymerization.

.. In the Oopm range, even if an elution test is performed with a simulated food liquid such as acid, alcohol, or oil, even an extremely sensitive ultraviolet spectrophotometer will not detect it, and virtually no elution will occur.
アントラキノン系ブルー染料の添加時期は、重合初期以
前、特に内温が260℃以下の時点が好ましい。重合中
期以降、後期に添加すると、調色の効果が小さいばかり
か、異物が発生する場合がある。The anthraquinone blue dye is preferably added before the initial stage of polymerization, especially when the internal temperature is 260° C. or lower. If added at the middle or late stage of polymerization, not only the toning effect will be small but also foreign matter may be generated.

It is 0 ppm. 0. If O is less than 5 ppm, the toning effect is small; 2. If it exceeds Oppm, the blue tint will be too strong, and if the base has a strong yellow tint due to the titanium catalyst, it may take on a green tint.

The transesterification reaction was carried out at 35°C. When no more distillate was produced, 0.3 parts of germanium oxide and 1.7 parts of an ethylene glycol solution of dihydroxymethyl phosphate (5.5 wt% as P) were added, and the mixture was transferred to a polymerization reaction tank. Here, a predetermined amount of 1,4-di(methylphenylamino)anthraquinone-3-sulfonic acid was added, and 260 to 27
The reaction was carried out at normal pressure at 0°C for about 15 minutes, and then at 280°C under high vacuum (high vacuum of several seconds or more) for about 3 hours. Thereafter, it was extracted from the polymerization reaction tank into a large amount of running water by a conventional method to obtain a strand-shaped chip with [η] of 0.53.

When DEG is low, the transparency of the bottle decreases, and AA becomes high, probably due to shear heat generation. On the other hand, if there is too much DEG, the hue will deteriorate due to thermal decomposition and the AA will also be high. In other toning agents, metals are detected, albeit in very small amounts.
