METHOD FOR PRODUCING FLUORINE POLYMER-CONTAINING AQUEOUS DISPERSION LIQUID

摘要

Provided is a method for producing a fluorine polymer-containing aqueous dispersion liquid which has excellent storage stability and is capable of providing a coating film that has excellent water resistance. When a monomer mixture containing fluoroolefin and a hydrophilic macromonomer is polymerized in the presence of an aqueous medium, polyoxyethylene alkyl ethers and a radical polymerization initiator, there are used polyoxyethylene alkyl ethers that include a polyoxyethylene alkyl ether which has an HLB value of 12-15 and in which the alkyl group is a linear alkyl group in an amount of 60-100% by mole relative to the total amount of the polyoxyethylene alkyl ethers.
