Abstract: The invention relates to a low coagulum fluoropolymer latex containing little or no surfactant, and having a high fluoropolymer solids content. The polymerization is run at temperatures somewhat greater than typically used. The latex can be dried into a solid resin, in which little or no surfactant is present, without using an ion exchange, washing, or other added unit operation. The invention also relates to the process for forming the high solids, latex, using little or no surfactant.
