Abstract
Described herein is a method of making a fluoropolymer and fluoropolymers thereof, wherein the method comprises: (a) providing an aqueous solution comprising a water soluble polyiodide salt of Formula (I): M+y[I—I—(I)Jy− wherein M is a cation group having a valence y, y is an integer of at least 1 and n is an integer of at least 1; and (b) initiating polymerization of a monomer in the aqueous solution, wherein the monomer is a fluorinated monomer.

A method of making a fluoropolymer comprising:
- (a) providing an aqueous solution comprising a water soluble polyiodide salt of Formula (I):
- M+y[I—I—(I)n]y−
- wherein M is a cation having a valence y, y is an integer of at least 1 and n is an integer of at least 1;
- and
- (b) initiating polymerization of a monomer in the aqueous solution, wherein the monomer is a fluorinated monomer.
A fluoropolymer obtainable by polymerizing a fluorinated monomer in the presence of a water soluble polyiodide salt of Formula (I):
- M+y[I—I—(I)n]y−
- wherein M is a cation group having a valence y, y is an integer of at least 1 and n is an integer of at least 1.
A partially fluorinated polymer comprising:
- a polymer chain comprising terminal groups consisting of side groups and end groups, wherein the polymer chain comprises at least one terminal group comprising —CH2I and is substantially free of terminal groups comprising —CF2I wherein the partially fluorinated polymer is polymerized in the absence of a diiodo compound of the formula I—Z—I, wherein Z is selected from one of an alkyl group, partially fluorinated alkyl group or a perfluorinated alkyl group.
