Title:
PROCESS FOR PRODUCTION OF FLUORINE-CONTAINING POLYMER LATEX
Document Type and Number:
WIPO Patent Application WO/2011/105347
Kind Code:
A1
Abstract:
A fluorine-containing polymer latex which exhibits environmental degradability and has a remarkably reduced emulsifier residue content can be produced by emulsion polymerization of a fluorine-containing monomer using an emulsifier that consists of a perfluoroalkylalkylphosphonic acid salt represented by the general formula: CnF2n+1CmH2mP(O)(OM1)(OM2) [wherein M1 is hydrogen, an alkali metal, or ammonium; M2 is an alkali metal or ammonium, ammonium being preferable; n is an integer of 2 to 6; and m is an integer of 1 to 3]. The fluorine-containing polymer latex exhibits emulsion stability equivalent or superior to that of a fluorine-containing polymer latex prepared using a perfluorooctanoic acid (salt) as the emulsifier.
