Decrease method of fluoro surface active agent content ratio of the fluoro polymer dispersed liquid which uses the anionic exchange resin which was processed with the anionic surface active agent

摘要

Decrease method of fluoro surface active agent content ratio of stabilization fluoro surface active agent content water fluoro polymer dispersed liquid. This method includes the process which offers the fixed bed of the anionic exchange resin which possesses the counter ion equipped anionic exchange basis. The anionic exchange resin is processed in order to replace at least how much of the counter ions with the counter ion of the non fluorine conversion anionic surface active agent. The stabilization fluoro surface active agent content water fluoro polymer dispersed liquid passes to the fixed bed where the anionic exchange resin was processed.
