Formula (2):
[(R 3 ) 3 R 4 P] + · CF 3 SO 3 − (2)
(Wherein R 3 represents an alkyl group having 4 to 8 carbon atoms, and R 4 represents an alkyl group having 8 to 20 carbon atoms) (hereinafter referred to as phosphonium salt (2)). The present invention relates to an antistatic agent characterized by containing an antistatic agent and an antistatic resin composition comprising the antistatic agent.
本発明のホスホニウム塩(1)は優れた帯電防止能を有する。またホスホニウム塩(2)を有効成分として含有する帯電防止剤は、樹脂に用いることで、従来に比べてより低い表面抵抗値を示す帯電防止性樹脂組成物を製造できうる。 The phosphonium salt (1) of the present invention has an excellent antistatic ability. Moreover, the antistatic agent which contains phosphonium salt (2) as an active ingredient can manufacture the antistatic resin composition which shows a surface resistance value lower than before by using for resin.

反応終了後の反応液は、ホスホニウム塩(1)の水溶解性が低いので、水層と有機層とに分液している。この反応液からホスホニウム塩(1)を分離するには、所望により有機層を水洗した後、有機層を濃縮することによってホスホニウム塩(1)が得られる。また、必要であれば水不溶の有機溶剤(例えば、トルエン、酢酸エチル、塩化メチレン等)を反応中又は反応終了後に添加し、ホスホニウム塩(1)を水不溶の有機溶剤に抽出してもよく、得られた抽出層を所望により水洗し、次いで有機溶剤を留出除去して抽出層を濃縮すれば残渣として、ホスホニウム塩(1)が得られる。 The reaction solution after completion of the reaction is separated into an aqueous layer and an organic layer because the water solubility of the phosphonium salt (1) is low. In order to separate the phosphonium salt (1) from this reaction solution, the organic layer is washed with water if desired, and then the phosphonium salt (1) is obtained by concentrating the organic layer. If necessary, a water-insoluble organic solvent (for example, toluene, ethyl acetate, methylene chloride, etc.) may be added during or after the reaction to extract the phosphonium salt (1) into the water-insoluble organic solvent. The obtained extraction layer is washed with water if desired, and then the organic solvent is distilled off and the extraction layer is concentrated to obtain the phosphonium salt (1) as a residue.

By adding such an antistatic agent to the resin during the production of the resin composition, the surface resistance value is further reduced as compared with a conventional antistatic agent containing a phosphonium salt. A resin composition can be produced. Furthermore, since the phosphonium salts of the present invention are hydrophobic, it is expected that the effect of antistatic performance due to humidity is small.
