Title
(EN) STERICALLY-HINDERED ALKYL HYDROXYLAMINES FOR SCAVENGING OF FREE RADICALS
(FR) ALKYLHYDROXYLAMINES A EMPECHEMENT STERIQUE PERMETTANT LA DESTRUCTION DES RADICAUX LIBRES
Abstract
(EN)
Free radical scavengers are formed from sterically-hindered alkylhydroxylamines. The free radical scavengers are believed useful to interrupt polymerization reactions or to facilitate storage and transportation of reactive monomers. Free radical scavengers preferably have formula (I).
(FR)
L'invention se rapporte à des phagocytes de radicaux libres qui sont formés à partir d'alkylhydroxylamines à empêchement stérique. Ces phagocytes de radicaux libres s'avèrent utiles pour interrompre les réactions de polymérisation ou pour faciliter le stockage et le transport de monomères réactifs. Ces phagocytes de radicaux libres sont de préférence représentés par la formule (I).
