ABSTRACT:
A process comprising polymerizing at least one fluorinated monomer in an aqueous medium containing initiator and polymerization agent to form an aqueous dispersion of particles of fluoropolymer, the polymerization agent comprising fluoropolyether acid or salt thereof having a number average molecular weight of at least about 800 g/mol; and fluoropolyether acid or salt surfactant.
