Abstract

Acylhydrazones phénoliques à empéchement stérique. Il s'agit plus particulièrement de 3-(3',5'-di-t-butyl-4'-hydroxyphényl)propionyl hydrazones de divers alcanals et alcanones dont la chaîne peut comporter un atome de soufre et/ou un groupe carboxylate. Utilisation pour la protection de matières organiques diverses contre la chaleur et l'oxydation, plus spécialement pour la stabilisation de caoutchoucs de diènes, comme le polybutadiène et le polyisoprène.
