    摘要: An emulsion polymerization process for the production of fluoroelastomers is disclosed wherein at least one fluorosurfactant is employed as dispersant, said fluorosurfactant being a fluoroalkylphosphoric acid ester of the formula X—Rf-(CH2)n—O—P(O)(OM)2, wherein n=1 or 2, X=H or F, M=a univalent cation, and Rf is a C4-C6 fluoroalkyl or fluoroalkoxy group. Optionally, a second dispersing agent may be employed in the polymerization, said second agent being a perfluoropolyether having at least one endgroup selected from the group consisting of carboxylic acid, a salt thereof, sulfonic acid and a salt thereof, phosphoric acid and a salt thereof.

    摘要: 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.
