(57) Abstract: (a) 6-hydroxychroman compound, (B) a phosphorus-based antioxidant selected from a biphenylenephosphonite compound, an aryl phosphite compound, a pentaerythritol phosphite compound, and an oxaphosphine compound; and (c) a phenol-based antioxidant; ), Component (b) and component (c), component (a) in an amount of 0.5% by weight to 10% by weight, The total amount of component (b) and component (c) is from 99.5% by weight to 9%. An organic polymer material stabilizer composition containing 0% by weight, and an organic polymer material composition obtained by blending the above organic polymer material stabilizer composition with an organic polymer. [Effect] By using the stabilizer composition of the present invention as a stabilizer for an organic polymer material, a stabilized organic polymer material composition excellent in processing stability and extremely industrially useful can be obtained. be able to. |
