Definitions
- the present invention relates to a method for producing a terminal-treated vinylidene fluoride elastomer containing a group having a specific structure at one or both ends of a main chain.
- Fluoropolymers are widely used in the automobile industry, semiconductor industry, chemical industry and the like because they exhibit excellent chemical resistance, solvent resistance and heat resistance.
- fluorine-containing polymers in which a crosslinkable functional group is introduced at the end of the fluorine-containing polymer have been developed, and a method for easily and efficiently introducing a crosslinkable functional group is desired. ing.
- Japanese Patent Application Laid-Open No. 2005-307026 discloses a functional fluorine-containing polymer material having a sulfonic acid group at the graft chain end in a fluorine-based polymer.
- a resin containing 5 mol% of trifluorobromoethylene in polytetrafluoroethylene is used, and the amount of sulfonic acid groups introduced is about 0.5 meq / g. Therefore, since the reactivity is poor and a large number of functional end groups cannot be introduced, there is a disadvantage that conversion of Rf-X to sulfonic acid in the proposed method is not always easy.
- Prog. Polymn. Sci. 1989, 14, 251-296. And JP-T-2002-514242 describe a polymerization method including starting with a persulfate such as ammonium persulfate or potassium persulfate. Thermally initiated free radical polymerization using reducing agents such as sodium sulfite and sodium hydrogen sulfite and persulfates is described to produce polymers having both carboxylic acid and sulfonic acid end groups. . According to this method, a polymer having the same functional group as a terminal group cannot be obtained, and therefore, the reactivity of the terminal group is different, making it difficult to use as a polymer intermediate.
