Abstract:
(EN) The purpose of the present invention is to obtain a polytetrafluoroethylene aqueous dispersion liquid from which fluorine-containing compounds have been removed or diminished. The present invention is a method for producing a purified polytetrafluoroethylene aqueous dispersion liquid, the method being characterized by including a step of removing or diminishing compounds represented by general formula (1) or (2) from a polytetrafluoroethylene aqueous dispersion liquid obtained using a hydrocarbon-based surfactant. General formula (1): (H-(CF2)m-COO)pM1 General formula (2): (H-(CF2)n-SO3)qM2
(FR) La présente invention a pour objet d'obtenir une dispersion aqueuse liquide de polytétrafluoréthylène, dont les composés fluorés ont été éliminés ou diminués.
