Microemulsion polymerization process for the production of small polytetrafluoroethylene polymer particles

摘要

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.
