| 摘要 |
<p>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 (.001-.1 micrometer) preferably 1 to 80 (.001-.08 micrometer), more preferably 5 to 100 nanometer (.005-.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.</p> |
