Title:
METHOD FOR POLYMERIZING WATER-DISPERSIBLE EMULSION OF FLUORINE MONOMERS CONTAINING VINYLIDENE FLUORIDE
Document Type and Number:
WIPO Patent Application WO/2012/074196
Kind Code:
A2
Abstract:
The present invention relates to a method for preparing fluorine-based polymers containing vinylidene fluoride, the method comprising the steps of: dissolving fluorosulfonate-based surfactant or polyfluorocarboxylate surfactant in water and inputting the resultant solution into a polymerization reactor (step 1); adding fluorine monomers containing vinylidene fluoride and an initiator into the polymerization reactor to initiate an emulsion polymerization reaction (step 2); preparing fluorine-based polymers containing vinylidene fluoride through polymerization by adding a chain transfer agent to the polymerization reactor (step 3); and purging the reactor after the reaction and discharging a dispersion liquid (step 4).
