A perfluoropolyether thiol compound comprises a perfluoropolyether segment, at least one mercapto group (—SH), and at least one intervening divalent carbonylimino moiety (—C(═O)—NR—, wherein R is hydrogen or alkyl). The compound can be produced, for example, by a ring-opening reaction of thiolactones with perfluoropolyether-substituted, primary or secondary amines. The compound can be used, for example, as a polymerization chain transfer agent, as an intermediate for the preparation of functional group-containing fluorochemical derivatives such as disulfides, and as a fluorinated surface treatment.
一种全氟聚醚硫醇化合物,包括一个全氟聚醚段,至少一个巯基(—SH),以及至少一个介于二价的羰基亚胺基团(—C(═O)—NR—, 其中R为氢或烷基)。例如,该化合物可以通过巯内酯与全氟聚醚取代的一级或二级胺的环开合反应制备。该化合物可以用作聚合链转移剂,用于制备含官能团的氟化学衍生物如二硫化物的中间体,以及用于氟化表面处理。
