METHOD OF NEW FLUORINATED POLYMERS PRODUCTION |
摘要 |
The invention is a solution/dispersion composition comprising a perfluorinated polymer containing sites convertible to ion exchange groups dissolved in a solvent/dispersant having: a boiling point of less than 110 DEG C; a density of from 1.55 to 2.97 grams per cubic centimeter, and a solubility parameter of from greater than 7.1 up to 8.2 hildebrands. Particularly preferred is a solvent/dispersant having the general formula: XCF2-CYZX' wherein: X is selected from F, Cl, Br, and I; X' is selected from Cl, Br, and I; Y and Z are independently selected from H, F, Cl, Br, I and R'; R' is selected from perfluoroalkyl radicals and chloroperfluoroalkyl radicals having from 1 to 6 carbon atoms. The most preferred solvent is 1,2-dibromotetrafluoroethane. |
