Abstract
Provided is a method for producing a fluorinated polymer with suppressed generation of hydrophilic group-containing by-products. The method for producing a fluorinated polymer according to the present invention includes polymerizing a monomer including a fluorine-containing monomer with the use of a polymerization initiator X, in an aqueous dispersion containing a hydrocarbon-containing surfactant and an aqueous medium, to obtain a fluorinated polymer, wherein the polymerization initiator X contains no hydrophilic group and has a molecular weight of 200 or less.
Claims12
A method for producing a fluorinated polymer, comprising polymerizing a monomer including a fluorine-containing monomer with the use of a polymerization initiator X, in an aqueous dispersion containing a hydrocarbon-containing surfactant and an aqueous medium, to obtain a fluorinated polymer,
- wherein the polymerization initiator X contains no hydrophilic group and has a molecular weight of 200 or less.
An aqueous dispersion comprising:
