Title:
METHOD FOR PRODUCING AQUEOUS DISPERSION OF FLUORINE-CONTAINING ELASTOMER
Document Type and Number:
WIPO Patent Application WO/2022/030389
Kind Code:
A1
Abstract:
Provided is a method for producing an aqueous dispersion of a fluorine-containing elastomer. In the method, an aqueous dispersion of a fluorine-containing elastomer is produced by polymerizing a fluorine-containing monomer in the presence of an aqueous medium and a polymer (1) containing a polymerization unit derived from at least one type of monomer (1) selected from the group consisting of vinylphosphonic acid, vinylsulfonic acid, (meth)acrylic acid, itaconic acid, maleic acid, crotonic acid, fumaric acid, vinyl acetate and salts of these.
