Abstract: front page image
(EN)Polyhydroxy curable fluoroelastomers that are substantially free of nucleophilic endgroups are grafted with a monophenol having at least one pendant group. The resulting grafted fluoroelastomers retain most of the properties of the original elastomers including excellent pre-vulcanization characteristics, while incorporating pendant groups which may be used for further modification, crosslinking or for changing the physical properties (e.g. Tg) of the fluoroelastomer.
(FR)Des élastomères fluorés réparables polyhydroxy substantiellement libres de groupes terminaux nucléophiliques sont greffés avec un monphénol comportant au moins un groupe pendant. Les fluoroélastomères greffés qui en résultent conservent la plupart des propriétés des élastomères originaux incluant d’excellentes caractéristiques de pré-vulcanisation tout en incorporant des groupes pendants qui peuvent être utilisés pour des modifications additionnelles, pour la réticulation, ou pour altérer les propriétés physiques (par exemple, Tg) de l’élastomère fluore.
