    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.

    Abstract: Microspheres are described which have a shell of thermally expandable polymer and a hollow interior that contains a fluorinated hydrocarbon that boils at a temperature below the melting point of the polymer, and contains an organic ester or ether or ketone. The ester or ether or ketone improves the quality of microsphere product. The expandable particles are useful in insulation, packaging, for expanding other polymer such as polytetrafluoroethylene, and the like.
