ABSTRACT:
In this invention an aqueous seeded microemulsion polymerization procedure is provided in which colloidal polymer particles are produced from tetrafluoroethylene or tetrafluoroethylene/comonomer or other polymerizable monomers. The particles have an average diameter between 1 to 100 nanometer (0.001-0.1 micrometer) preferably 1 to 80 (0.001-0.08 micrometer), more preferably 5 to 100 nanometer (0.005-0.1 micrometer). A microemulsion is formed of a liquid monomer in water and a gaseous monomer is added either before or after polymerization is initiated.
