Title
(EN) METHOD OF MAKING FLUOROPOLYMERS
(FR) PROCEDE DE FABRICATION DE POLYMERES FLUORES
Abstract
(EN)
A process for making a fluoropolymer is disclosed. The process comprises solubilizing a fluoromonomer in solvent comprising a carbon dioxide fluid, and then polymerizing the fluoromonomer to produce a fluoropolymer. A preferred solvent for carrying out the process is supercritical carbon dioxide; preferred fluoromonomers for carrying out the process are fluoroacrylate monomers such as 1,1-dihydroperfluorooctyl acrylate. The polymerization step is preferably carried out in the presence of an initiator such as azobisisobutyronitrile.

L'invention concerne un procédé de fabrication d'un polymère fluoré. Le procédé consiste à solubiliser un monomère fluoré dans un solvant qui contient un fluide de dioxyde de carbone, puis à polymériser le monomère fluoré pour obtenir le polymère fluoré. Du dioxyde de carbone supercritique est de préférence utilisé comme solvant pour effectuer le procédé, et des monomères de fluoroacrylate, tels que l'acrylate de 1,1-dihydroperfluoro-octyle, sont de préférence utilisés comme fluoromonomères pour effectuer le procédé. L'étape de polymérisation est de préférence effectuée en présence d'un agent d'amorçage tel que l'azobisisobutyronitrile.
