Abstract
An aqueous microemulsion polymerization procedure is described in which very small colloidal polymer particles are produced from tetrafluoroethylene monomer. The polymerization procedure involves adding a free-radical initiator to a mixture of a microemulsion of at least one liquid saturated organic compound; and tetrafluoroalkyl ethylene.
