Provided are: a thermal stabilizer composition which does not generate an odor of a phosphorus-based antioxidant; and a synthetic resin composition comprising the same. The thermal stabilizer composition comprises: 100 parts by mass of a phosphorus-based antioxidant having a phosphite structure; and 0.001 to 10 parts by mass of a phenolic antioxidant having a substructure represented by the following Formula (1):
(wherein, R1, R2, R3 and R4 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; a represents an integer of 0 to 2; and, when a is 2, plural R3s are optionally the same or different).
本文提供了:一种不会产生磷基抗氧化剂气味的热稳定剂组合物;以及一种包含该热稳定剂组合物的合成树脂组合物。热稳定剂组合物包括质量分数为 100 的具有亚磷酸酯结构的磷基抗氧化剂;以及质量分数为 0.001 至 10 的具有下式 (1) 所表示的亚结构的酚类抗氧化剂:
(其中,R1、R2、R3 和 R4 各自独立地代表氢原子或具有 1 至 10 个碳原子的烃基;a 代表 0 至 2 的整数;当 a 为 2 时,多个 R3 可选择相同或不同)。
