    摘要: Tetrakis(2,4-di-tert-butyl-5-methylphenyl)-4,4'-biphenylenediphosphonite, stabilizers for organic materials, which contain said compound, and stabilized organic materials containing said compound as a stabilizer. The tetrakis(2,4-di-tert-butyl-5-methylphenyl)-4,4'-biphenylenediphosphonite has particularly superior hydrolysis resistance, and is characterized in that it has superior storage stability due to its scarce hygroscopicity. It can be purified and handled easily since it is in a powder form, and it shows less volatility at high temperatures. By using the compound of the present invention as a stabilizer for organic materials, extremely useful organic materials imparted with superior processing stability, heat resistance and resistance to oxidative degradation can be provided.
