| titleOfInvention | Tetrafluoroethylene copolymer |
| abstract | A polymerization method for producing a tetrafluoroethylene copolymer and a copolymer produced by the method are provided. The copolymer is in a dispersed / fine powder form, polymerized tetrafluoroethylene monomer units and of the formula: (C n F (2n + 1) ) CH═CH 2 where 6 ≦ n <10. Containing a copolymerized higher homologue comonomer unit, the primary particles are considered to have a core-shell structure, and the polymerized comonomer unit is 0.01 mol% to 0.3 mol based on the entire copolymer composition. % Present. The copolymer has a primary dispersed primary particle size (RDPS) of less than 0.210 μm and a standard specific gravity (SSG) of the copolymer of less than 2.143. The copolymer has comonomer units present in an amount of 0.05 mol% to 0.25 mol%, and the RDPS is in the range of 0.178 μm to 0.200 μm and the SSG is less than 2.140 It is preferable. Copolymers produced in accordance with the present invention, (perfluorohexyl) ethylene (PFHE) and (perfluorooctyl) ethylene (PFOE) can be formed into the shape of a stretched bead having a diameter of 0.1 inch, and the stretch bead has a breaking strength of at least It can be 10.0 pounds and can exceed 13.0 pounds. [Selection figure] None |
