PCT No. PCT/US93/01626 Sec. 371 Date Sep. 27, 1994 Sec. 102(e) Date Sep. 27, 1994 PCT Filed Feb. 26, 1993 PCT Pub. No. WO93/20116 PCT Pub. Date Oct. 14, 1993.A process for making a fluoropolymer is disclosed. The process comprises solubilizing a fluoromonomer in solvent comprising a carbon dioxide fluid, and then polymerizing the fluoromonomer to produce the fluoropolymer. A preferred solvent for carrying out the process is supercritical carbon dioxide; preferred fluoromonomers for carrying out the process are fluoroacrylate monomers such as 1,1-dihydroperfluorooctyl acrylate. The polymerization step is preferably carried out in the presence of an initiator such as azobisisobutyronitrile.
