摘要： An aqueous microemulsion polymerization procedure is described in which very small colloidal melt-processible fluoropolymer particles are produced from at least one gaseous monomer and optionally TFE. The polymerization procedure involves forming a microemulsion of at least one liquid saturated organic compound; adding at leat one gaseous free-radical polymerizable monomer to the microemulsion; and initiating polymerization by adding a free-radical initiator to the mixture.

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 forming a microemulsion of at least one liquid saturated organic compound; adding gaseous tetrafluoroalkyl monomer to the microemulsion; and initiating polymerization by adding a free-radical initiator to the mixture.

摘要： Novel polytetrafluoroethylene structures are described, which were prepared by polymerizing liquid tetrafluoroethylene in aqueous dispersion. The novel structures include continuous three-dimensional networks of fibrils and bundles of fibrils.
