查询词典 chloric ether

The structure of sulfonated polys from DB is similar to that of sulfonated poly(arylene thioether phosphine oxide)s from TB. The latter could be regarded as the"product"of the former provided that the ether unit of the former was replaced by the thioether unit. The studies illustrated that the latter exhibited much better oxidative stability than the former. This is due to the fact that the thioether unit of the former was oxidized into the sulfone or sulfoxide unit in Fenton reagent, which inactivated the adjacent benzene rings and thus retarded the degradation reaction.

从结构上看，后者可以看成是前者的醚基团被硫醚基团取代后的&产物&，其耐氧化性能比前者好得多，这是因为后者的硫醚基团在Fenton试剂中被氧化成为砜或亚砜基团，而砜或亚砜基是钝化基团，钝化了与之相连的苯环，阻碍了降解反应。
