Abstract
An aqueous microemulsion polymerization procedure is described in which very small colloidal melt-processible fluoropolymer particles are produced from at least one gaseous monomer and optionally TFE. The polymerization procedure involves forming a microemulsion of at least one liquid organic compound; adding at least one gaseous free-radical polymerizable monomer to the microemulsion; and initiating polymerization by adding a free-radical initiator to the mixture.
