Beschreibung
Zusammenfassung:	The present invention generally relates to compounds and methods for preventing fouling caused by the radical polymerization of unsaturated compounds, particularly vinyl monomers. More particularly, it relates to the use of hindered hydroquinones to inhibit the polymerization, which result in the fouling of process equipment, and prematurely consume the vinylic monomer products. La présente invention concerne d'une manière générale des composés et des procédés pour empêcher l'encrassement provoqué par la polymérisation radicalaire de composés insaturés, notamment de monomères vinyliques L'invention concerne plus particulièrement l'utilisation d'hydroquinones à encombrement pour inhiber la polymérisation entraînant l'encrassement d'équipements de processus et consommant prématurément les produits de monomères vinyliques.
