| titleOfInvention | Method for manufacturing fluoroelastomers |
| abstract | The invention pertains to a process for manufacturing a fluoroelastomer [fluoroelastomer (A)] having a heat of fusion of less than 5 J/g as measured by ASTM D-3418-08, said method comprising emulsion polymerizing vinylidene fluoride (VDF) in the presence of at least one additional fluorinated monomer, in an aqueous polymerization medium, said method comprising polymerizing VDF and said additional fluorinated monomer(s) in the presence of a redox radical initiator system comprising: - at least one organic oxidizing agent [agent (O)]; - at least one organic reducing agent [agent (R)]; wherein agent (O) is fed to said polymerization medium separately from agent (R), so that agent (O) comes in contact with agent (R) exclusively in said polymerization medium comprising VDF and optional additional monomer(s), to fluoroelastomers having low amount of chain defects and low amount of polar end groups, notably obtainable from said process, and to curable compositions therefrom. |
