Aqueous polymerization of fluorinated monomer using polymerization agent comprising high molecular weight fluoropolyether acid or salt and fluoropolyether acid or salt surfactant
Abstract
The invention claims a device comprising a including the initiator and the polymerizing agent aqueous medium in the polymerization of at least one fluorinated monomers to form a fluoropolymer particle aqueous dispersion of a method for the polymerizing agent comprises number average molecular weight of at least about 800 g/mol fluoro- polyether acid or its salt; And fluorine-containing polymer acid or hydrochloric ether surface active agent.
