に導入する方法は恒久的な制電性を与える点で最も有効
なものとされ、すでに実用化されているものもある。Various methods have been tried to suppress this charging property, but the method of introducing ionic or nonionic surfactants, metal powder, carbon black, etc. into the synthetic polymer during polymerization or molding has not resulted in permanent control. It is said to be the most effective in providing electricity, and some are already in practical use.
しかしながら、これらの帯電防止剤は合成重合体中への
分散が悪かったり、合成重合体の性質を低下させたりす

特に溶融成形して繊維やフィルムを形成させる場合には
、溶融した重合体組成物が高温で安定であることが要求
され帯電防止剤添加による耐熱性低下や成形性低下が問
題となっている。Particularly when melt molding is used to form fibers or films, the molten polymer composition is required to be stable at high temperatures, and the addition of an antistatic agent poses a problem of decreased heat resistance and moldability.

たものである。In view of these circumstances, the present inventors have conducted intensive research and found that by dispersing 5n-Ti in a synthetic polymer that can be melt-molded, the inventors have achieved dispersibility without impairing the original excellent properties of the synthetic polymer. The present invention as described at the beginning was achieved by discovering that a permanent antistatic effect can be obtained with good moldability and moldability.

られる。In the present invention, the melt-moldable synthetic polymer refers to a synthetic polymer that can be formed into fibers or films by melt-proofing or melt-extrusion molding, and specific examples include polyamides such as nylon 6 and nylon 66, and polyethylene. Examples include polyesters such as terephthalate and polybutylene terephthalate, and polyolefins such as polyethylene and polypropylene.

でもよく、コーテイング量は酸化第二錫として酸化チタ
ンに対して１０〜５０重量φであることが望ましい。Next, in the case of 5n-Ti used in the present invention, titanium oxide fine particles are usually immersed in a solution of tin salt, for example, an aqueous solution of tin chloride, and the surface is coated with tin salt. The tin salt used in this case may be either a stannous salt or a stannic salt, and the coating amount is 10 to 50% as stannic oxide relative to titanium oxide. It is desirable that the weight is φ.
また、粒子は合成重合体中への分散をよくするためでき
るだけ小さいものが望ましく、通常０．１〜５０ミクロ
ン程度のものが使用される。Further, the particles are preferably as small as possible in order to improve dispersion into the synthetic polymer, and particles of about 0.1 to 50 microns are usually used.
また、５ｎ−Ｔｉの合成重合体への配合量は組成物の３
〜２０重量係とすることが望ましい。In addition, the amount of 5n-Ti added to the synthetic polymer is 3% of the composition.
It is desirable to set it as 20 to 20 weight ratios.
３重量幅より少ない量では良好な制電効果が発揮されな
い場合があり、２０重重量上り多い量では粒子の分散性
の低下、合成重合体の品質劣化につながる場合があるか
らである。This is because if the amount is less than 3 weight range, a good antistatic effect may not be exhibited, and if the amount is more than 20 weight weight, it may lead to a decrease in the dispersibility of the particles and a deterioration in the quality of the synthetic polymer.
しかし、配合量は要求される性能、用途等によって適宜
調節される。However, the blending amount is appropriately adjusted depending on the required performance, usage, etc.
５ｎ−Ｔｉの合成重合体への配合は成形以前の任意の段
階でなされるが、配合時には粒子の分散をできるだけ均
一にするため溶融状態で攪拌混合することが好ましい。5n-Ti can be blended into the synthetic polymer at any stage before molding, but during blending, it is preferable to stir and mix the 5n-Ti in a molten state in order to make the particle dispersion as uniform as possible.

。In the present invention, a master polymer containing a large amount of 5n-Ti is prepared and blended with other fusible synthetic polymers, and the surface of a non-antistatic synthetic polymer is made to have antistatic properties obtained by the present invention. These include those wrapped in polymeric compositions, which are often useful for improving runnability and improving the quality of synthetic polymers.
