Abstract
The invention relates to a method of polymerizing at least one monomer comprising a vinylidene fluoride monomer, the method comprising putting in contact the at least one monomer with a polymerization initiator and an oxidizing agent, the polymerization initiator having the formula (I): (RfSO2−)xMx+ (II) wherein Rf is a fluoroalkyl group comprising from 1 to 3 carbon atoms; and Mx+ is chosen from a monovalent cation, or a divalent cation, or a trivalent cation, or a tetravalent cation.
Claims14
A method of polymerizing at least one monomer comprising a vinylidene fluoride monomer, the method comprising putting in contact the at least one monomer with a polymerization initiator and an oxidizing agent, the polymerization initiator having the formula (I):
- (RfSO2−)xMx+ (I)
- wherein:
- Rf is a fluoroalkyl group comprising from 1 to 3 carbon atoms;
- and
- Mx+ comprises a monovalent cation, a divalent cation, a trivalent cation, or a tetravalent cation,
- wherein the method is carried out in the absence of a surfactant.
