primary and secondary antioxidant, i.e. a phenolic and a thioether moiety in an optimized spatial arrangement. The mechanism of their intramolecular synergism was investigated. The best overall stabilizers are 2,4-bis(alkylthiomethyl)-6-methylphenols, e.g. AOl, in contrast to 2,6-dialkyl-4-alkylthiomethylphenols(B), 4-alkyl-2,6-bis(alkylthiomethyl)phenols C.
烷基-羟基苄基硫醚是弹性体和粘合剂的有效储存和加工稳定剂。特别是烷基-(2-羟基苄基)硫醚代表一级和二级抗氧化剂的分子内组合,即优化空间排列的酚类和硫醚部分。研究了它们分子内协同作用的机制。最好的整体稳定剂是 2,4-双(烷硫基甲基)-6-甲基苯酚,例如 AOl,与 2,6-二烷基-4-烷硫基甲基苯酚(B)、4-烷基-2,6-双(烷硫基甲基)苯酚相比C。
