Title:
METHOD FOR PRODUCING AQUEOUS FLUOROPOLYMER DISPERSION, DRAINAGE TREATMENT METHOD, AND AQUEOUS FLUOROPOLYMER DISPERSION
Document Type and Number:
WIPO Patent Application WO/2020/218620
Kind Code:
A1
Abstract:
Provided is a method for producing an aqueous fluoropolymer dispersion, the method being characterized by including a step A in which an untreated aqueous dispersion, which contains a fluoropolymer (where a polymer (I) is excluded) obtained by performing polymerization in the presence of the polymer (I) including a polymerization unit (I) based on a monomer represented by general formula (I), is subjected to a ultrafiltration, microfiltration, or dialysis membrane treatment, or a combination thereof. CX1X3=CX2R(-CZ1Z2-A0)m (I) (In the formula, X1 and X3 are each independently F, Cl, H, or CF3; X2 is H, F, an alkyl group, or a fluorine-containing alkyl group; A0 is an anionic group; R is a linking group; Z1 and Z2 are each independently H, F, an alkyl group, or a fluorine-containing alkyl group; and m is an integer of 1 or more.)
