Title
(EN) OXYGENATED AMINOPHENOL COMPOUNDS AND METHODS FOR PREVENTING MONOMER POLYMERIZATION
(FR) COMPOSÉS D'AMINOPHÉNOL OXYGÉNÉS ET PROCÉDÉS DE PRÉVENTION DE LA POLYMÉRISATION DE MONOMÈRES
Abstract
(EN)
Described are compounds, compositions, and methods that include a nitrogen- and oxygen-containing aromatic compound, such as an aminophenol-based compound, which can be used for inhibiting polymerization of a monomer (e.g., styrene) composition. The compound includes a tertiary amine group wherein] the nitrogen is attached to carbon-containing groups, and at least one of oxygen atom separated from the nitrogen by one or more carbon atoms. The antipolymerant can provide excellent antipolymerant activity in a monomer-containing composition.
(FR)
L'invention concerne des composés, des compositions et des procédés comprenant un composé aromatique contenant de l'azote et de l'oxygène, tel qu'un composé à base d'aminophénol, qui peut être utilisé pour inhiber la polymérisation d'une composition de monomère (par exemple, le styrène). Le composé comprend un groupe amine tertiaire, l'azote étant fixé à des groupes contenant du carbone, et au moins un atome d'oxygène séparé de l'azote par un ou plusieurs atomes de carbone. L'agent antipolymérisation peut fournir une excellente activité antipolymérisation dans une composition contenant un monomère.
