General description
TEMPO, polymer-bound (PS-TEMPO) has been synthesized via nitroxide catalyzed radical polymerization of styrene. TEMPO end-capped polystyrene (PS-TEMPO) copolymers have been synthesized for the modification of multi-walled carbon nanotubes (MWNTs). Synthesis of PS-TEMPO from polystyrene, benzoyl peroxide and TEMPO has been reported. Grafting of TEMPO onto polystyrene has been proposed via copper(I)-catalyzed azide-alkyne cycloaddition reaction.
Features and Benefits
Free radical catalyst.

TEMPO（2,2,6,6-四甲基哌啶氧基或2,2,6,6-四甲基哌啶1-氧基）及其衍生物在有机氧化反应催化剂中可以作为稳定的硝酰基使用。TEMPO由Lebedev和Kazarnovskii于1960年发现，其具有的稳定自由基性质得益于其庞大的取代基团阻碍了自由基与其他分子之间发生反应。
