Improved aqueous emulsion polymerization process for producing fluoropolymers |
| abstract |
The present invention provides a method of making a fluoropolymer through emulsionnpolymerization of one or more fluorinated monomers in an aqueous phase in the presencenof a fluorinated surfactant. At least part of the fluorinated surfactant is added to thenaqueous phase as an aqueous mixture with at least one organic liquid that is not misciblenwith water and that is selected from halogenated and non-halogenated organic liquids, thenmixture having droplets having an average droplet diameter of not more than 1000nm andnthe mixture being added to the aqueous phase in such an amount that the total amount ofnthe fluorinated surfactant is not more than 1% by weight based on the weight of thenaqueous phase and the total amount of said organic liquid is not more than 1 % by weightnbased on the weight of said aqueous phase. n The invention allows for an improvement of the efficiency of an aqueous emulsionnpolymerization process. In particular, the polymerization time can be reduced and thenpolymer yield may be improved. |
