Radical Polymerization of N-(4-Diphenylamino) Acrylamide under High Pressure
It is well known  that when hindered arylamines are attacked by peroxy radicals they scavenge the radicals to form very stable nitroxy radicals. The stable radicals thus formed further scavenge other radicals. Because of these properties, these Compounds are excellent antioxidants for synthetic polymers . Moreover, some unsaturated monomers bearing hindered arylamine groups capable of forming stable radicals have been prepared  and their radical polymerizability has been studied  with some kinds of radical initiators. The polymerization normally goes only when 2,2’-azobisisobutryonitrile is used, while other initiators such as benzoyl peroxide, cumene hydroperoxide, and tetraethylthiuram disulfide inhibit the polymerization remarkably or completely.
