| titleOfInvention | Method for producing fluoroelastomer |
| abstract | ΩH perfluorocarboxylic acid represented by the general formula H (CF 2 ) n COOM (where M is a hydrogen atom, alkali metal or ammonium group, and n is 6, 7 or 8) or a salt thereof as an emulsifier A fluoroelastomer is produced by polymerizing a fluorinated olefin. The fluoroelastomer produced by the method of the present invention has a low Mooney viscosity ML 1 + 10 (121 ° C.) as a result of the polymerization reaction of the fluorinated olefin using ωH perfluorocarboxylic acid (salt) as an emulsifier, and injection molding. Since the fluidity essential as a material for use is improved, productivity at the time of injection molding is improved. In addition, there is no particular decrease in the polymerization rate during the polymerization reaction, and there is no decrease in physical properties such as tensile strength, compression set resistance and tear resistance during heat resistance. |
