Document Type and Number:
Japanese Patent JP4226722
Kind Code:
B2
Abstract:
A process for preparing a solution and/or dispersion containing sulphonic (per)fluorinated ionomers having -SO3M functional groups, wherein M is selected from H, Li, Na, K, NR4 (R equal to or different from each other are selected from H, CH3,C2H5), characterized in that it dissolves the above defined ionomers at a temperature comprised between the room temperature and about 150 DEG C, in a monophasic ternary mixture essentially constituted by water, by a C1-C4 alcohol and by a fluoro(poly)oxyalkylene having one hydrogen atom in at least a fluorinated end group; the dispersed polymer particle sizes are in the range 30-100 nm.
