    • The present invention relates to a stabilizer composition for organic polymer material containing (a) 6-hydroxychroman compound, a phosphorus antioxidant and (c) phenolic antioxidant, wherein the component (a) is contained in a proportion of 0.5 wt %-10 wt % and the total amount of the component (b) and the component (c) is in a proportion of 99.5 wt %-90 wt %, of the total amount of the components (a), (b) and (c). The present invention also relates to an organic polymer material composition containing an organic polymer and the above-mentioned stabilizer composition for organic polymer material. The use of the stabilizer composition of the present invention as a stabilizer for organic polymer materials affords an industrially extremely useful stabilized organic polymer material composition superior in heat stability during processing.
    • 本发明涉及含有(a)6-羟基苯并二氢吡喃化合物,磷抗氧化剂和(c)酚类抗氧化剂的有机聚合物材料稳定剂组合物,其中组分(a)的含量为0.5重量%-10重量% 组分(b)和组分(c)的总量占组分(a),(b)和(c)总量的99.5重量%-90重量%的比例。 本发明还涉及包含有机聚合物和上述有机聚合物材料的稳定剂组合物的有机聚合物材料组合物。 使用本发明的稳定剂组合物作为有机聚合物材料的稳定剂提供了在加工过程中热稳定性优异的工业上非常有用的稳定的有机聚合物材料组合物。
