Title:
METHOD FOR PRODUCING FLUORINE-CONTAINING ELASTOMER AQUEOUS DISPERSION, AND COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/107891
Kind Code:
A1
Abstract:
The present invention provides a method for producing a fluorine-containing elastomer aqueous dispersion, wherein 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) that contains a polymerization unit (1) based on a monomer (1) that is represented by general formula (1). (1): CF2=CF-R-CZ1Z2-COOM
(In the formula, R represents a linking group; each of Z1 and Z2 independently represents F or CF3; M represents H, a metal atom, NR7
4, an optionally substituted imidazolium, an optionally substituted pyridinium or an optionally substituted phosphonium; and R7 represents H or an organic group.)
