Title (EN) PROCESS FOR PRODUCING POLYFLUOROALKYL ESTER AND PROCESS FOR PRODUCING FLUORINATED ACRYLIC COPOLYMER FROM THE ESTER
(FR) METHODE DE PREPARATION D'UN POLYFLUOROALKYL ESTER ET METHODE DE PRODUCTION D'UN COPOLYMERE ACRYLIQUE FLUORE AU MOYEN DE L'ESTER AINSI OBTENU
Abstract: front page image
(EN)A polyfluoroalkyl iodide is reacted with a metal salt of (meth)acrylic acid to form the corresponding polyfluoroalkyl (meth)acrylate. The polyfluoroalkyl (meth)acrylate is separated and recovered from the reaction products by evaporation. Thus, the polyfluoroalkyl iodide can be reacted with the metal salt of (meth)acrylic acid while avoiding water inclusion to produce the polyfluoroalkyl (meth)acrylate. This ester can be copolymerized with an ethylenically unsaturated compound copolymerizable therewith.
(FR)On fait réagir un polyfluoroalkyl iodure avec un sel métallique d'acide (méth)acrylique, afin de former le polyfluoroalkyl (méth)acrylate correspondant. On sépare et on récupère le polyfluoroalkyl (méth)acrylate des produits de réaction par évaporation. Ainsi, on peut faire réagir le polyfluoroalkyl iodure avec le sel métallique d'acide (méth)acrylique, en évitant un ajout d'eau pour produire le polyfluoroalkyl (méth)acrylate. Cet ester peut être copolymérisé avec un composé éthylèniquement insaturé.
