Title:
METHOD FOR MANUFACTURING FLUORINE-CONTAINING ELASTOMER AQUEOUS DISPERSION, FLUORINE-CONTAINING ELASTOMER, AND AQUEOUS DISPERSION
Document Type and Number:
WIPO Patent Application WO/2022/025190
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a fluorine-containing elastomer aqueous dispersion in which a fluorine-containing monomer is polymerized in the presence of an aqueous medium and a fluorine-containing compound (1) represented by general formula (1), whereby an aqueous dispersion of a fluorine-containing elastomer is manufactured.　General formula (1): CX1X2=CX3-Z (where X1 to X3 are independently H, F, or a fluorine-containing alkyl group; if both X1 and X2 are H, X3 is F or a fluorine-containing alkyl group; Z is a group represented by -COOM, -SO3M, -OSO3M, -PO(OM)2, -OPO(OM)2, -BO(OM)2, or -OBO(OM)2; M is H, a metal atom, NR1 4, imidazoleium that may have a substitutent, pyridinium that may have a substituent, or phosphonium that may have a substituent; R1 is independently H or an organic group, and any two R1 may be bonded to each other to form a ring).
